Password Reset & MFA Implementation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Add self-service password reset and TOTP MFA with per-tenant enforcement to Cameleer SaaS.

Architecture: Password reset uses Logto Experience API from the custom sign-in UI (no backend changes). MFA enrollment uses Logto Management API via new backend endpoints. Per-tenant enforcement via mfa_enrolled JWT claim + settings.mfaRequired tenant config. Backup codes for recovery.

Tech Stack: Logto Experience API, Logto Management API, Spring Security filter, React 19, qrcode.react, @cameleer/design-system

Spec: docs/superpowers/specs/2026-04-26-password-reset-mfa-design.md

Task 1: Password Reset — Experience API Functions

Files:

• Modify: ui/sign-in/src/experience-api.ts

• Step 1: Add forgot-password API functions

Append after the // --- Registration --- section:

// --- Forgot Password ---

export async function initForgotPassword(): Promise<void> {
  const res = await request('PUT', '', { interactionEvent: 'ForgotPassword' });
  if (!res.ok) {
    const err = await res.json().catch(() => ({}));
    throw new Error(err.message || `Failed to initialize password reset (${res.status})`);
  }
}

export async function forgotPasswordSendCode(email: string): Promise<string> {
  const res = await request('POST', '/verification/verification-code', {
    identifier: { type: 'email', value: email },
    interactionEvent: 'ForgotPassword',
  });
  if (!res.ok) {
    const err = await res.json().catch(() => ({}));
    if (res.status === 422) {
      throw new Error('No account found with this email');
    }
    throw new Error(err.message || `Failed to send reset code (${res.status})`);
  }
  const data = await res.json();
  return data.verificationId;
}

export async function forgotPasswordVerifyAndReset(
  email: string,
  verificationId: string,
  code: string,
  newPassword: string,
): Promise<void> {
  const verifiedId = await verifyCode(email, verificationId, code);
  await identifyUser(verifiedId);
  await addProfile('password', newPassword);
  await submitInteraction();
}

export async function startForgotPassword(email: string): Promise<string> {
  await initForgotPassword();
  return forgotPasswordSendCode(email);
}

• Step 2: Add MFA verification API functions

Append after the forgot-password section:

// --- MFA Verification ---

export async function verifyTotp(code: string): Promise<string> {
  const res = await request('POST', '/verification/totp/verify', { code });
  if (!res.ok) {
    const err = await res.json().catch(() => ({}));
    if (res.status === 422) {
      throw new Error('Invalid code, please try again');
    }
    throw new Error(err.message || `TOTP verification failed (${res.status})`);
  }
  const data = await res.json();
  return data.verificationId;
}

export async function verifyBackupCode(code: string): Promise<string> {
  const res = await request('POST', '/verification/backup-code/verify', { code });
  if (!res.ok) {
    const err = await res.json().catch(() => ({}));
    if (res.status === 422) {
      const msg = err.code === 'backup_code_consumed'
        ? 'This backup code has already been used'
        : 'Invalid backup code';
      throw new Error(msg);
    }
    throw new Error(err.message || `Backup code verification failed (${res.status})`);
  }
  const data = await res.json();
  return data.verificationId;
}

export async function submitMfa(verificationId: string): Promise<string> {
  await identifyUser(verificationId);
  return submitInteraction();
}

• Step 3: Update signIn() to detect MFA requirement

Replace the existing signIn function:

export class MfaRequiredError extends Error {
  constructor() {
    super('MFA verification required');
    this.name = 'MfaRequiredError';
  }
}

export async function signIn(identifier: string, password: string): Promise<string> {
  await initInteraction();
  const verificationId = await verifyPassword(identifier, password);
  await identifyUser(verificationId);
  const res = await request('POST', '/submit');
  if (!res.ok) {
    const err = await res.json().catch(() => ({}));
    if (err.code === 'user.missing_mfa') {
      throw new MfaRequiredError();
    }
    throw new Error(err.message || `Submit failed (${res.status})`);
  }
  const data = await res.json();
  return data.redirectTo;
}

Also update the import in SignInPage.tsx (next task) to import MfaRequiredError.

• Step 4: Update the SignInPage import line

In ui/sign-in/src/SignInPage.tsx, change the import to:

import {
  signIn, startRegistration, completeRegistration,
  startForgotPassword, forgotPasswordVerifyAndReset,
  verifyTotp, verifyBackupCode, submitMfa,
  MfaRequiredError,
} from './experience-api';

• Step 5: Commit

git add ui/sign-in/src/experience-api.ts ui/sign-in/src/SignInPage.tsx
git commit -m "feat: add forgot-password and MFA verification Experience API functions"

Task 2: Password Reset <20><><EFBFBD> Sign-in UI

Files:

• Modify: ui/sign-in/src/SignInPage.tsx

• Modify: ui/sign-in/src/SignInPage.module.css

• Step 1: Extend the Mode type and add state

Change the Mode type and add new state variables:

type Mode = 'signIn' | 'register' | 'verifyCode' | 'forgotPassword' | 'forgotPasswordVerify' | 'mfaVerify' | 'mfaBackupCode';

Add state for forgot-password fields inside SignInPage(), after the existing verificationId state:

const [newPassword, setNewPassword] = useState('');
const [confirmNewPassword, setConfirmNewPassword] = useState('');

• Step 2: Add emailConnectorConfigured state

The "Forgot password?" link should only show when an email connector is configured. The existing registrationEnabled check covers the signInMode, but forgot-password needs an email connector regardless of registration state. Add state derived from the sign-in experience fetch.

After the existing setRegistrationEnabled(enabled) line in the useEffect, add:

// Email connector is configured if sign-in-exp has passwordless methods or signUp has email verification
// For simplicity: if the response loads successfully and has connectorTargets or if registration is enabled
// (both require a configured email connector), forgot-password is available.
const hasEmailConnector = enabled || (data.forgotPassword?.email ?? false);
setEmailConnectorConfigured(hasEmailConnector);

Add the state variable:

const [emailConnectorConfigured, setEmailConnectorConfigured] = useState(false);

Actually, simpler: the forgot-password email template is always configured in EmailConnectorService when the email connector exists. The sign-in experience fetch returns the full config. Check for signUp.verify or the connector being present. The cleanest approach: if registrationEnabled is true, the email connector must be configured. But forgot-password should also work when registration is disabled but email connector exists. The safest check: fetch the connectors list. But that's an extra API call.

Pragmatic approach: show "Forgot password?" whenever an email connector exists. The sign-in experience signUp object has identifiers that include email when email connector is configured, even if registration is disabled. Check:

const hasEmailConnector = Array.isArray(data.signUp?.identifiers) && data.signUp.identifiers.includes('email');
setEmailConnectorConfigured(hasEmailConnector);

• Step 3: Add forgot-password handler

After handleVerifyCode, add:

// --- Forgot password step 1: send reset code ---
const handleForgotPassword = async (e: FormEvent) => {
  e.preventDefault();
  setError(null);
  if (!identifier.includes('@')) {
    setError('Please enter your email address');
    return;
  }
  setLoading(true);
  try {
    const vId = await startForgotPassword(identifier);
    setVerificationId(vId);
    setMode('forgotPasswordVerify');
  } catch (err) {
    setError(err instanceof Error ? err.message : 'Failed to send reset code');
  } finally {
    setLoading(false);
  }
};

// --- Forgot password step 2: verify code + set new password ---
const handleForgotPasswordVerify = async (e: FormEvent) => {
  e.preventDefault();
  setError(null);
  if (newPassword !== confirmNewPassword) {
    setError('Passwords do not match');
    return;
  }
  if (newPassword.length < 8) {
    setError('Password must be at least 8 characters');
    return;
  }
  setLoading(true);
  try {
    await forgotPasswordVerifyAndReset(identifier, verificationId, code, newPassword);
    // Send security notification email (fire-and-forget)
    fetch('/platform/api/password-reset-notification', {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify({ email: identifier }),
    }).catch(() => {});
    // Reset to sign-in with success message
    switchMode('signIn');
    setError(null);
    // Using a simple approach — show a transient success state
    setIdentifier(identifier); // preserve email for convenience
    alert('Password reset successful. Please sign in with your new password.');
  } catch (err) {
    setError(err instanceof Error ? err.message : 'Password reset failed');
  } finally {
    setLoading(false);
  }
};

• Step 4: Add "Forgot password?" link to sign-in form

In the sign-in form JSX, after the password FormField closing tag and before the <Button> submit, add:

{emailConnectorConfigured && (
  <button
    type="button"
    className={styles.forgotLink}
    onClick={() => { setError(null); setMode('forgotPassword'); }}
  >
    Forgot password?
  </button>
)}

• Step 5: Add forgot-password email entry form

After the {/* --- Verification code form --- */} block (before </div></Card>), add:

{/* --- Forgot password: email entry --- */}
{mode === 'forgotPassword' && (
  <form className={styles.fields} onSubmit={handleForgotPassword} aria-label="Reset password" noValidate>
    <p className={styles.verifyHint}>
      Enter your email address and we'll send you a code to reset your password.
    </p>

    <FormField label="Email" htmlFor="forgot-email">
      <Input
        id="forgot-email"
        type="email"
        value={identifier}
        onChange={(e) => setIdentifier(e.target.value)}
        placeholder="you@company.com"
        autoFocus
        autoComplete="email"
        disabled={loading}
      />
    </FormField>

    <Button
      variant="primary"
      type="submit"
      loading={loading}
      disabled={loading || !identifier}
      className={styles.submitButton}
    >
      Send reset code
    </Button>

    <p className={styles.switchText}>
      <button type="button" className={styles.switchLink} onClick={() => switchMode('signIn')}>
        Back to sign in
      </button>
    </p>
  </form>
)}

{/* --- Forgot password: verify code + new password --- */}
{mode === 'forgotPasswordVerify' && (
  <form className={styles.fields} onSubmit={handleForgotPasswordVerify} aria-label="Set new password" noValidate>
    <p className={styles.verifyHint}>
      We sent a verification code to <strong>{identifier}</strong>
    </p>

    <FormField label="Verification code" htmlFor="forgot-code">
      <Input
        id="forgot-code"
        type="text"
        inputMode="numeric"
        value={code}
        onChange={(e) => setCode(e.target.value.replace(/\D/g, '').slice(0, 6))}
        placeholder="000000"
        autoFocus
        autoComplete="one-time-code"
        disabled={loading}
      />
    </FormField>

    <FormField label="New password" htmlFor="forgot-new-password">
      <div className={styles.passwordWrapper}>
        <Input
          id="forgot-new-password"
          type={showPassword ? 'text' : 'password'}
          value={newPassword}
          onChange={(e) => setNewPassword(e.target.value)}
          placeholder="At least 8 characters"
          autoComplete="new-password"
          disabled={loading}
        />
        {passwordToggle}
      </div>
    </FormField>

    <FormField label="Confirm new password" htmlFor="forgot-confirm-password">
      <Input
        id="forgot-confirm-password"
        type={showPassword ? 'text' : 'password'}
        value={confirmNewPassword}
        onChange={(e) => setConfirmNewPassword(e.target.value)}
        placeholder="••••••••"
        autoComplete="new-password"
        disabled={loading}
      />
    </FormField>

    <Button
      variant="primary"
      type="submit"
      loading={loading}
      disabled={loading || code.length < 6 || !newPassword || !confirmNewPassword}
      className={styles.submitButton}
    >
      Reset password
    </Button>

    <p className={styles.switchText}>
      <button type="button" className={styles.switchLink} onClick={() => switchMode('forgotPassword')}>
        Back
      </button>
    </p>
  </form>
)}

• Step 6: Update switchMode to reset new fields

In the switchMode function, add resets for the new state:

const switchMode = (next: Mode) => {
  setMode(next);
  setPassword('');
  setConfirmPassword('');
  setNewPassword('');
  setConfirmNewPassword('');
  setCode('');
  setShowPassword(false);
  setVerificationId('');
};

• Step 7: Add forgotLink CSS

In SignInPage.module.css, add after .switchLink:hover:

.forgotLink {
  background: none;
  border: none;
  cursor: pointer;
  color: var(--text-muted);
  font-size: 13px;
  padding: 0;
  text-decoration: underline;
  text-align: right;
  align-self: flex-end;
  margin-top: -8px;
}

.forgotLink:hover {
  color: var(--text-link, #C6820E);
}

• Step 8: Commit

git add ui/sign-in/src/SignInPage.tsx ui/sign-in/src/SignInPage.module.css
git commit -m "feat: add forgot-password UI flow to custom sign-in page"

Task 3: MFA Verification at Sign-in — UI

Files:

• Modify: ui/sign-in/src/SignInPage.tsx

• Modify: ui/sign-in/src/SignInPage.module.css

• Step 1: Update handleSignIn to catch MfaRequiredError

Replace the existing handleSignIn:

const handleSignIn = async (e: FormEvent) => {
  e.preventDefault();
  setError(null);
  setLoading(true);
  try {
    const redirectTo = await signIn(identifier, password);
    window.location.replace(redirectTo);
  } catch (err) {
    if (err instanceof MfaRequiredError) {
      setMode('mfaVerify');
      setLoading(false);
      return;
    }
    setError(err instanceof Error ? err.message : 'Sign-in failed');
    setLoading(false);
  }
};

• Step 2: Add MFA verification handlers

After handleForgotPasswordVerify, add:

// --- MFA: TOTP verification ---
const handleMfaVerify = async (e: FormEvent) => {
  e.preventDefault();
  setError(null);
  setLoading(true);
  try {
    const verificationId = await verifyTotp(code);
    const redirectTo = await submitMfa(verificationId);
    window.location.replace(redirectTo);
  } catch (err) {
    setError(err instanceof Error ? err.message : 'Verification failed');
    setLoading(false);
  }
};

// --- MFA: backup code verification ---
const handleBackupCodeVerify = async (e: FormEvent) => {
  e.preventDefault();
  setError(null);
  setLoading(true);
  try {
    const verificationId = await verifyBackupCode(code);
    const redirectTo = await submitMfa(verificationId);
    window.location.replace(redirectTo);
  } catch (err) {
    setError(err instanceof Error ? err.message : 'Verification failed');
    setLoading(false);
  }
};

• Step 3: Add MFA verification forms

After the forgot-password forms, before </div></Card>, add:

{/* --- MFA: TOTP verification --- */}
{mode === 'mfaVerify' && (
  <form className={styles.fields} onSubmit={handleMfaVerify} aria-label="Two-factor authentication" noValidate>
    <p className={styles.verifyHint}>
      Enter the 6-digit code from your authenticator app.
    </p>

    <FormField label="Authentication code" htmlFor="mfa-totp-code">
      <Input
        id="mfa-totp-code"
        type="text"
        inputMode="numeric"
        value={code}
        onChange={(e) => setCode(e.target.value.replace(/\D/g, '').slice(0, 6))}
        placeholder="000000"
        autoFocus
        autoComplete="one-time-code"
        disabled={loading}
      />
    </FormField>

    <Button
      variant="primary"
      type="submit"
      loading={loading}
      disabled={loading || code.length < 6}
      className={styles.submitButton}
    >
      Verify
    </Button>

    <div className={styles.backupCodeCard}>
      <p className={styles.backupCodeText}>Lost your device?</p>
      <button
        type="button"
        className={styles.backupCodeAction}
        onClick={() => { setCode(''); setError(null); setMode('mfaBackupCode'); }}
      >
        Use a backup code
      </button>
    </div>
  </form>
)}

{/* --- MFA: backup code verification --- */}
{mode === 'mfaBackupCode' && (
  <form className={styles.fields} onSubmit={handleBackupCodeVerify} aria-label="Backup code verification" noValidate>
    <p className={styles.verifyHint}>
      Enter one of your 10 backup codes.
    </p>

    <FormField label="Backup code" htmlFor="mfa-backup-code">
      <Input
        id="mfa-backup-code"
        type="text"
        value={code}
        onChange={(e) => setCode(e.target.value)}
        placeholder="Enter backup code"
        autoFocus
        autoComplete="off"
        disabled={loading}
      />
    </FormField>

    <Button
      variant="primary"
      type="submit"
      loading={loading}
      disabled={loading || !code}
      className={styles.submitButton}
    >
      Verify backup code
    </Button>

    <p className={styles.switchText}>
      <button type="button" className={styles.switchLink} onClick={() => { setCode(''); setError(null); setMode('mfaVerify'); }}>
        Use authenticator app instead
      </button>
    </p>
  </form>
)}

• Step 4: Add backup code card CSS

In SignInPage.module.css, add:

.backupCodeCard {
  margin-top: 4px;
  padding: 12px 16px;
  background: var(--bg-surface, #f8f7f5);
  border: 1px solid var(--border-default, #e8e0d4);
  border-radius: 6px;
  text-align: center;
}

.backupCodeText {
  font-size: 13px;
  color: var(--text-muted);
  margin: 0 0 6px;
}

.backupCodeAction {
  background: none;
  border: none;
  cursor: pointer;
  color: var(--text-link, #C6820E);
  font-size: 14px;
  font-weight: 600;
  padding: 4px 8px;
  text-decoration: underline;
}

.backupCodeAction:hover {
  opacity: 0.8;
}

• Step 5: Commit

git add ui/sign-in/src/SignInPage.tsx ui/sign-in/src/SignInPage.module.css
git commit -m "feat: add MFA verification (TOTP + backup code) to sign-in flow"

Task 4: Logto Bootstrap — MFA Config + JWT Claim

Files:

• Modify: docker/logto-bootstrap.sh

• Step 1: Add MFA factors to Phase 8c sign-in experience patch

In docker/logto-bootstrap.sh, find the Phase 8c PATCH call (the PATCH /api/sign-in-exp with signInMode and signIn.methods). Add the mfa field to the same JSON payload. The full patched call becomes:

api_patch "/api/sign-in-exp" '{
  "signInMode": "SignIn",
  "signIn": {
    "methods": [
      {
        "identifier": "email",
        "password": true,
        "verificationCode": false,
        "isPasswordPrimary": true
      },
      {
        "identifier": "username",
        "password": true,
        "verificationCode": false,
        "isPasswordPrimary": true
      }
    ]
  },
  "mfa": {
    "factors": ["Totp", "BackupCode"],
    "policy": "UserControlled"
  }
}'

• Step 2: Extend custom JWT script in Phase 7b

Replace the existing CUSTOM_JWT_SCRIPT variable with the extended version that includes mfa_enrolled:

CUSTOM_JWT_SCRIPT='const getCustomJwtClaims = async ({ token, context, environmentVariables }) => {
  const roleMap = { owner: "server:admin", operator: "server:operator", viewer: "server:viewer" };
  const roles = new Set();
  if (context?.user?.organizationRoles) {
    for (const orgRole of context.user.organizationRoles) {
      const mapped = roleMap[orgRole.roleName];
      if (mapped) roles.add(mapped);
    }
  }
  if (context?.user?.roles) {
    for (const role of context.user.roles) {
      if (role.name === "saas-vendor") roles.add("server:admin");
    }
  }
  const mfaFactors = context?.user?.mfaVerificationFactors || [];
  const mfaEnrolled = mfaFactors.some(f => f.type === "Totp");
  const claims = {};
  if (roles.size > 0) claims.roles = [...roles];
  claims.mfa_enrolled = mfaEnrolled;
  return claims;
};'

• Step 3: Commit

git add docker/logto-bootstrap.sh
git commit -m "feat: configure MFA factors + mfa_enrolled JWT claim in Logto bootstrap"

Task 5: Backend — LogtoManagementClient MFA Methods

Files:

• Modify: src/main/java/net/siegeln/cameleer/saas/identity/LogtoManagementClient.java

• Step 1: Add getUserMfaVerifications method

Add after the existing updateUserPassword method:

/** List all MFA verifications for a user. Returns a list of MFA factor objects. */
public List<Map<String, Object>> getUserMfaVerifications(String userId) {
    if (!isAvailable()) return List.of();
    try {
        String token = getAccessToken();
        String response = restClient.get()
                .uri(logtoConfig.getEndpoint() + "/api/users/{userId}/mfa-verifications", userId)
                .header("Authorization", "Bearer " + token)
                .retrieve()

    } catch (Exception e) {
        log.warn("Failed to delete MFA verification {} for user {}: {}", verificationId, userId, e.getMessage());
    }

• Step 5: Add deleteAllMfaVerifications method

/** Delete all MFA verifications for a user (used for admin MFA reset). */
public void deleteAllMfaVerifications(String userId) {

Task 6: Backend — MFA Portal Endpoints

Files:

• Modify: src/main/java/net/siegeln/cameleer/saas/portal/TenantPortalService.java

• Modify: src/main/java/net/siegeln/cameleer/saas/portal/TenantPortalController.java

• Step 1: Add MFA methods to TenantPortalService

Add these methods to TenantPortalService:

public record MfaStatusData(boolean enrolled, boolean hasBackupCodes) {}

public record MfaSetupData(String secret, String secretQrCode) {}

public record BackupCodesData(List<String> codes) {}

public MfaStatusData getMfaStatus(String userId) {

    return new MfaStatusData(hasTotp, hasBackup);
}

public MfaSetupData setupTotp(String userId) {

    String qrCode = (String) result.getOrDefault("secretQrCode", "");
    return new MfaSetupData(secret, qrCode);
}

public boolean verifyTotpCode(String secret, String code) {
    // TOTP verification: compute expected code from secret and compare
    // Uses the same algorithm as authenticator apps (RFC 6238)
    long timeStep = System.currentTimeMillis() / 1000 / 30;
    for (int i = -1; i <= 1; i++) { // allow 1 step drift
        String expected = computeTotp(secret, timeStep + i);
        if (expected.equals(code)) return true;
    }
    return false;
}

private String computeTotp(String base32Secret, long timeStep) {
    try {
        byte[] key = new org.apache.commons.codec.binary.Base32().decode(base32Secret);
        byte[] data = java.nio.ByteBuffer.allocate(8).putLong(timeStep).array();
        javax.crypto.Mac mac = javax.crypto.Mac.getInstance("HmacSHA1");
        mac.init(new javax.crypto.spec.SecretKeySpec(key, "HmacSHA1"));
        byte[] hash = mac.doFinal(data);
        int offset = hash[hash.length - 1] & 0xf;
        int binary = ((hash[offset] & 0x7f) << 24) | ((hash[offset + 1] & 0xff) << 16)
                | ((hash[offset + 2] & 0xff) << 8) | (hash[offset + 3] & 0xff);
        int otp = binary % 1_000_000;
        return String.format("%06d", otp);
    } catch (Exception e) {
        throw new IllegalStateException("TOTP computation failed", e);
    }
}

public BackupCodesData generateBackupCodes(String userId) {
    var result = logtoClient.createBackupCodes(userId);
    @SuppressWarnings("unchecked")
    List<String> codes = (List<String>) result.getOrDefault("codes", List.of());
    return new BackupCodesData(codes);
}

public void removeTotp(String userId) {
    var verifications = logtoClient.getUserMfaVerifications(userId);
    for (var v : verifications) {
        String id = String.valueOf(v.get("id"));
        logtoClient.deleteMfaVerification(userId, id);
    }
}

public void resetTeamMemberMfa(String userId) {
    // Verify the user is a member of this tenant's org
    var tenant = tenantService.getById(TenantContext.getTenantId())
            .orElseThrow(() -> new IllegalStateException("Tenant not found"));
    String orgId = tenant.getLogtoOrgId();
    var members = logtoClient.listOrganizationMembers(orgId);
    boolean isMember = members.stream().anyMatch(m ->
            userId.equals(m.get("id")) || userId.equals(m.get("userId")));
    if (!isMember) {
        throw new IllegalArgumentException("User is not a member of this organization");
    }
    logtoClient.deleteAllMfaVerifications(userId);
}

• Step 2: Add MFA endpoints to TenantPortalController

Add these endpoints to TenantPortalController:

@GetMapping("/mfa/status")
public ResponseEntity<?> getMfaStatus(@AuthenticationPrincipal Jwt jwt) {
    try {
        return ResponseEntity.ok(portalService.getMfaStatus(jwt.getSubject()));
    } catch (Exception e) {
        return ResponseEntity.internalServerError().body(Map.of("error", e.getMessage()));
    }
}

@PostMapping("/mfa/totp/setup")
public ResponseEntity<?> setupTotp(@AuthenticationPrincipal Jwt jwt) {
    try {
        return ResponseEntity.ok(portalService.setupTotp(jwt.getSubject()));
    } catch (Exception e) {
        return ResponseEntity.internalServerError().body(Map.of("error", e.getMessage()));
    }
}

public record TotpVerifyRequest(String secret, String code) {}

@PostMapping("/mfa/totp/verify")
public ResponseEntity<?> verifyTotp(
        @AuthenticationPrincipal Jwt jwt,
        @RequestBody TotpVerifyRequest request) {
    try {
        boolean valid = portalService.verifyTotpCode(request.secret(), request.code());
        if (!valid) {
            return ResponseEntity.status(422).body(Map.of("error", "Invalid TOTP code"));
        }
        // TOTP is already bound via setupTotp — verification confirms the user has the right secret
        return ResponseEntity.ok(Map.of("verified", true));
    } catch (Exception e) {
        return ResponseEntity.internalServerError().body(Map.of("error", e.getMessage()));
    }
}

@PostMapping("/mfa/backup-codes")
public ResponseEntity<?> generateBackupCodes(@AuthenticationPrincipal Jwt jwt) {
    try {
        return ResponseEntity.ok(portalService.generateBackupCodes(jwt.getSubject()));
    } catch (Exception e) {
        return ResponseEntity.internalServerError().body(Map.of("error", e.getMessage()));
    }
}

@DeleteMapping("/mfa/totp")
public ResponseEntity<?> removeTotp(@AuthenticationPrincipal Jwt jwt) {
    try {
        portalService.removeTotp(jwt.getSubject());
        return ResponseEntity.noContent().build();
    } catch (Exception e) {
        return ResponseEntity.internalServerError().body(Map.of("error", e.getMessage()));
    }
}

@DeleteMapping("/users/{userId}/mfa")
public ResponseEntity<?> resetTeamMemberMfa(@PathVariable String userId) {
    try {
        portalService.resetTeamMemberMfa(userId);
        return ResponseEntity.noContent().build();
    } catch (IllegalArgumentException e) {
        return ResponseEntity.badRequest().body(Map.of("error", e.getMessage()));
    } catch (Exception e) {
        return ResponseEntity.internalServerError().body(Map.of("error", e.getMessage()));
    }
}

• Step 3: Add tenant settings PATCH endpoint

Add to TenantPortalController:

@PatchMapping("/settings")
public ResponseEntity<?> updateSettings(
        @RequestBody Map<String, Object> updates) {
    try {
        portalService.updateTenantSettings(updates);
        return ResponseEntity.ok().build();
    } catch (Exception e) {
        return ResponseEntity.internalServerError().body(Map.of("error", e.getMessage()));
    }
}

Add to TenantPortalService:

public void updateTenantSettings(Map<String, Object> updates) {
    var tenant = tenantService.getById(TenantContext.getTenantId())
            .orElseThrow(() -> new IllegalStateException("Tenant not found"));
    var settings = new java.util.HashMap<>(tenant.getSettings());
    // Only allow known settings keys
    if (updates.containsKey("mfaRequired")) {
        settings.put("mfaRequired", Boolean.TRUE.equals(updates.get("mfaRequired")));
    }
    tenant.setSettings(settings);
    tenantService.save(tenant);
}

• Step 4: Add MFA policy endpoint for server consumption

Add to TenantPortalController:

@GetMapping("/{slug}/mfa-policy")
public ResponseEntity<?> getMfaPolicy(@PathVariable String slug) {
    try {
        var tenant = tenantService.getBySlug(slug)
                .orElseThrow(() -> new IllegalArgumentException("Tenant not found"));
        boolean mfaRequired = Boolean.TRUE.equals(tenant.getSettings().get("mfaRequired"));
        return ResponseEntity.ok(Map.of("mfaRequired", mfaRequired));
    } catch (IllegalArgumentException e) {
        return ResponseEntity.notFound().build();
    }
}

Note: this endpoint must be accessible with M2M tokens. The existing /api/tenant/** path requires authenticated() in SecurityConfig, which accepts any valid JWT including M2M tokens.

• Step 5: Commit

git add src/main/java/net/siegeln/cameleer/saas/portal/TenantPortalService.java src/main/java/net/siegeln/cameleer/saas/portal/TenantPortalController.java
git commit -m "feat: add MFA enrollment, removal, and settings endpoints"

    public MfaEnforcementFilter(TenantService tenantService, ObjectMapper objectMapper) {
        this.tenantService = tenantService;
        this.objectMapper = objectMapper;
    }

    @Override

        // Only apply to tenant API paths
        if (!path.startsWith("/api/tenant/")) return true;
        // Exempt MFA enrollment and essential endpoints
        return EXEMPT_PREFIXES.stream().anyMatch(path::startsWith);
    }

            filterChain.doFilter(request, response);
            return;
        }

        Jwt jwt = jwtAuth.getToken();
        Boolean mfaEnrolled = jwt.getClaim("mfa_enrolled");

        // If user has MFA enrolled, no enforcement needed
        if (Boolean.TRUE.equals(mfaEnrolled)) {
            filterChain.doFilter(request, response);
            return;
        }

        // Check if tenant requires MFA
        var tenantId = TenantContext.getTenantId();
        if (tenantId == null) {
            filterChain.doFilter(request, response);
            return;

                "message", "Your organization requires multi-factor authentication"
        ));
    }
}

• Step 2: Register the filter in SecurityConfig

In SecurityConfig.java, add the filter after the OAuth2 resource server filter. In the filterChain method, add:

.addFilterAfter(mfaEnforcementFilter, org.springframework.security.oauth2.server.resource.web.BearerTokenAuthenticationFilter.class)

Inject the filter in the SecurityConfig constructor or method parameter:

@Bean
public SecurityFilterChain filterChain(HttpSecurity http, MfaEnforcementFilter mfaEnforcementFilter) throws Exception {
    // ... existing config ...
    http.addFilterAfter(mfaEnforcementFilter, 
        org.springframework.security.oauth2.server.resource.web.BearerTokenAuthenticationFilter.class);
    return http.build();
}

• Step 3: Commit

git add src/main/java/net/siegeln/cameleer/saas/config/MfaEnforcementFilter.java src/main/java/net/siegeln/cameleer/saas/config/SecurityConfig.java
git commit -m "feat: add MFA enforcement filter with APP_MFA_REQUIRED error code"

        this.notificationService = notificationService;
    }

    public record NotificationRequest(String email) {}

    @PostMapping
    public ResponseEntity<?> notify(@RequestBody NotificationRequest request) {
        if (request.email() == null || !request.email().contains("@")) {
            return ResponseEntity.badRequest().body(Map.of("error", "Invalid email"));
        }
        // Rate limit check
        String key = request.email().toLowerCase();
        RateLimit limit = rateLimits.compute(key, (k, existing) -> {
            long now = System.currentTimeMillis();
            if (existing == null || now - existing.windowStart > 600_000) {
                return new RateLimit(now, new AtomicInteger(1));
            }
            existing.count.incrementAndGet();
            return existing;
        });
        if (limit.count.get() > 3) {
            return ResponseEntity.status(429).body(Map.of("error", "Too many requests"));
        }
        // Fire-and-forget in a thread to not block the response
        notificationService.sendNotification(request.email());
        return ResponseEntity.ok(Map.of("sent", true));
    }

    private record RateLimit(long windowStart, AtomicInteger count) {}
}

• Step 4: Permit the notification endpoint in SecurityConfig

In SecurityConfig.java, add to the permitAll paths:

.requestMatchers("/api/password-reset-notification").permitAll()

Add this in the authorizeHttpRequests block, before the /api/onboarding/** line.

• Step 5: Commit

git add src/main/java/net/siegeln/cameleer/saas/notification/ src/main/resources/email-templates/password-reset-notification.html src/main/java/net/siegeln/cameleer/saas/config/SecurityConfig.java
git commit -m "feat: add password reset security notification email endpoint"

Task 9: Frontend — API Types and Hooks for MFA

Files:

• Modify: ui/src/types/api.ts

• Modify: ui/src/api/tenant-hooks.ts

• Modify: ui/src/api/client.ts

• Step 1: Add MFA types

In ui/src/types/api.ts, add at the end:

// MFA types
export interface MfaStatus {
  enrolled: boolean;
  hasBackupCodes: boolean;
}

export interface MfaSetupResponse {
  secret: string;
  secretQrCode: string;
}

export interface BackupCodesResponse {
  codes: string[];
}

Extend the existing TenantSettings interface:

export interface TenantSettings {
  name: string;
  slug: string;
  tier: string;
  status: string;
  serverEndpoint: string | null;
  createdAt: string;
  mfaRequired?: boolean;
}

• Step 2: Add MFA hooks

In ui/src/api/tenant-hooks.ts, add:

import type { DashboardData, TenantLicenseData, TenantSettings, AuditLogPage, AuditLogFilters, SsoConnector, CreateSsoConnectorRequest, SsoTestResult, MfaStatus, MfaSetupResponse, BackupCodesResponse } from '../types/api';

// ... existing hooks ...

// MFA hooks
export function useMfaStatus() {
  return useQuery<MfaStatus>({
    queryKey: ['tenant', 'mfa', 'status'],
    queryFn: () => api.get('/tenant/mfa/status'),
  });
}

export function useMfaSetup() {
  return useMutation<MfaSetupResponse, Error, void>({
    mutationFn: () => api.post('/tenant/mfa/totp/setup'),
  });
}

export function useMfaVerify() {
  const qc = useQueryClient();
  return useMutation<{ verified: boolean }, Error, { secret: string; code: string }>({
    mutationFn: (body) => api.post('/tenant/mfa/totp/verify', body),
    onSuccess: () => qc.invalidateQueries({ queryKey: ['tenant', 'mfa'] }),
  });
}

export function useMfaBackupCodes() {
  const qc = useQueryClient();
  return useMutation<BackupCodesResponse, Error, void>({
    mutationFn: () => api.post('/tenant/mfa/backup-codes'),
    onSuccess: () => qc.invalidateQueries({ queryKey: ['tenant', 'mfa'] }),
  });
}

export function useMfaRemove() {
  const qc = useQueryClient();
  return useMutation<void, Error, void>({
    mutationFn: () => api.delete('/tenant/mfa/totp'),
    onSuccess: () => qc.invalidateQueries({ queryKey: ['tenant', 'mfa'] }),
  });
}

export function useResetTeamMemberMfa() {
  const qc = useQueryClient();
  return useMutation<void, Error, string>({
    mutationFn: (userId) => api.delete(`/tenant/users/${userId}/mfa`),
    onSuccess: () => qc.invalidateQueries({ queryKey: ['tenant', 'team'] }),
  });
}

export function useUpdateTenantSettings() {
  const qc = useQueryClient();
  return useMutation<void, Error, Record<string, unknown>>({
    mutationFn: (updates) => api.patch('/tenant/settings', updates),
    onSuccess: () => qc.invalidateQueries({ queryKey: ['tenant', 'settings'] }),
  });
}

• Step 3: Add APP_MFA_REQUIRED interceptor to API client

In ui/src/api/client.ts, update the apiFetch function to detect the MFA enforcement 403:

if (response.status === 403) {
  const errorHeader = response.headers.get('X-Cameleer-Error');
  if (errorHeader === 'APP_MFA_REQUIRED') {
    // Redirect to settings page with MFA section
    window.location.href = '/platform/tenant/settings?mfa=required';
    throw new Error('MFA enrollment required');
  }
}

Add this after the existing 401 check and before the generic !response.ok check.

• Step 4: Commit

git add ui/src/types/api.ts ui/src/api/tenant-hooks.ts ui/src/api/client.ts
git commit -m "feat: add MFA types, hooks, and APP_MFA_REQUIRED interceptor"

Task 10: Frontend — MFA Enrollment on Settings Page

Files:

• Modify: ui/src/pages/tenant/SettingsPage.tsx

• Run: cd ui && npm install qrcode.react

• Step 1: Install qrcode.react

cd ui && npm install qrcode.react

• Step 2: Add MFA section to SettingsPage

Import the new hooks and QR component at the top of SettingsPage.tsx:

import { QRCodeSVG } from 'qrcode.react';
import {
  useMfaStatus, useMfaSetup, useMfaVerify, useMfaBackupCodes, useMfaRemove,
  useUpdateTenantSettings,
} from '../../api/tenant-hooks';
import { useScopes } from '../../auth/useScopes';

After the existing "Server Admin Password" Card, add the MFA enrollment Card. This is a substantial component — add it as a separate section inside the same SettingsPage function:

{/* --- MFA Section --- */}
<MfaSection />

Define MfaSection as a function inside SettingsPage (or above it):

function MfaSection() {
  const toast = useToast();
  const { data: mfaStatus, isLoading: mfaLoading } = useMfaStatus();
  const setupMfa = useMfaSetup();
  const verifyMfa = useMfaVerify();
  const generateCodes = useMfaBackupCodes();
  const removeMfa = useMfaRemove();

  const [setupData, setSetupData] = useState<{ secret: string; secretQrCode: string } | null>(null);
  const [totpCode, setTotpCode] = useState('');
  const [backupCodes, setBackupCodes] = useState<string[] | null>(null);
  const [savedCodes, setSavedCodes] = useState(false);
  const [showRemoveConfirm, setShowRemoveConfirm] = useState(false);

  const handleStartSetup = async () => {
    try {
      const data = await setupMfa.mutateAsync();
      setSetupData(data);
    } catch (err) {
      toast.error(err instanceof Error ? err.message : 'Failed to start MFA setup');
    }
  };

  const handleVerify = async () => {
    if (!setupData) return;
    try {
      await verifyMfa.mutateAsync({ secret: setupData.secret, code: totpCode });
      // Generate backup codes
      const codes = await generateCodes.mutateAsync();
      setBackupCodes(codes.codes);
      setSetupData(null);
      setTotpCode('');
      toast.success('MFA enabled successfully');
    } catch (err) {
      toast.error(err instanceof Error ? err.message : 'Invalid code');
    }
  };

  const handleRegenerateCodes = async () => {
    try {
      const codes = await generateCodes.mutateAsync();
      setBackupCodes(codes.codes);
      setSavedCodes(false);
      toast.success('New backup codes generated');
    } catch (err) {
      toast.error(err instanceof Error ? err.message : 'Failed to generate codes');
    }
  };

  const handleRemove = async () => {
    try {
      await removeMfa.mutateAsync();
      setShowRemoveConfirm(false);
      toast.success('MFA removed');
    } catch (err) {
      toast.error(err instanceof Error ? err.message : 'Failed to remove MFA');
    }
  };

  const handleCopyCodes = () => {
    if (backupCodes) {
      navigator.clipboard.writeText(backupCodes.join('\n'));
      toast.success('Backup codes copied');
    }
  };

  const handleDownloadCodes = () => {
    if (!backupCodes) return;
    const blob = new Blob([backupCodes.join('\n')], { type: 'text/plain' });
    const url = URL.createObjectURL(blob);
    const a = document.createElement('a');
    a.href = url;
    a.download = 'cameleer-backup-codes.txt';
    a.click();
    URL.revokeObjectURL(url);
  };

  if (mfaLoading) return <Card title="Two-Factor Authentication"><Spinner /></Card>;

• Step 3: Add MFA enforcement toggle (tenant admins only)

After the <MfaSection />, add the enforcement toggle — visible only to users with owner/operator scope:

<MfaEnforcementToggle />

function MfaEnforcementToggle() {
  const toast = useToast();
  const { hasScope } = useScopes();
  const { data: settings } = useTenantSettings();
  const updateSettings = useUpdateTenantSettings();
  const [showConfirm, setShowConfirm] = useState(false);

  // Only show for tenant admins (owners/operators)
  if (!hasScope('tenant:manage')) return null;

  const mfaRequired = settings?.mfaRequired ?? false;

  const handleToggle = async () => {
    if (!mfaRequired) {
      setShowConfirm(true);
      return;
    }
    // Disabling — no confirmation needed
    try {
      await updateSettings.mutateAsync({ mfaRequired: false });
      toast.success('MFA requirement disabled');
    } catch (err) {
      toast.error(err instanceof Error ? err.message : 'Failed to update settings');
    }
  };

  const handleConfirmEnable = async () => {
    try {
      await updateSettings.mutateAsync({ mfaRequired: true });
      setShowConfirm(false);
      toast.success('MFA requirement enabled');
    } catch (err) {
      toast.error(err instanceof Error ? err.message : 'Failed to update settings');
    }
  };

  return (
    <Card title="Organization Security">

Task 11: Frontend — Reset MFA on Team Page

Files:

• Modify: ui/src/pages/tenant/TeamPage.tsx

• Step 1: Import the new hook

Add to the imports in TeamPage.tsx:

import { useTenantTeam, useInviteTeamMember, useRemoveTeamMember, useResetTeamMemberPassword, useResetTeamMemberMfa } from '../../api/tenant-hooks';

• Step 2: Wire up the hook and add state

Inside the TeamPage component, add:

const resetMfa = useResetTeamMemberMfa();
const [mfaResetTarget, setMfaResetTarget] = useState<TeamMember | null>(null);

• Step 3: Add "Reset MFA" button to the Actions column

In the DataTable columns, in the Actions cell renderer, add a new button between "Reset Password" and "Remove":

<Button
  variant="secondary"
  size="small"
  onClick={() => setMfaResetTarget(member)}
>
  Reset MFA
</Button>

• Step 4: Add MFA reset confirmation dialog

After the existing password reset form, add:

{mfaResetTarget && (
  <Card title={`Reset MFA for ${mfaResetTarget.name || mfaResetTarget.email}`} style={{ marginTop: 16 }}>
    <Alert variant="warning">
      This will remove all MFA factors for this user. They will need to re-enroll if MFA is required.
    </Alert>
    <div style={{ display: 'flex', gap: 8, marginTop: 16 }}>
      <Button
        variant="danger"
        onClick={async () => {
          try {
            await resetMfa.mutateAsync(mfaResetTarget.id);
            toast.success(`MFA reset for ${mfaResetTarget.name || mfaResetTarget.email}`);
            setMfaResetTarget(null);
          } catch (err) {
            toast.error(err instanceof Error ? err.message : 'Failed to reset MFA');
          }
        }}
        loading={resetMfa.isPending}
      >
        Confirm Reset MFA
      </Button>
      <Button variant="secondary" onClick={() => setMfaResetTarget(null)}>Cancel</Button>
    </div>
  </Card>
)}

• Step 5: Commit

git add ui/src/pages/tenant/TeamPage.tsx
git commit -m "feat: add Reset MFA action for team members"

Task 12: Server Handoff Document

Files:

• Create: docs/superpowers/specs/2026-04-26-server-mfa-handoff.md

• Step 1: Write the handoff doc

# Cameleer-Server MFA Handoff Document

**Date:** 2026-04-26
**For:** cameleer-server team
**Context:** The SaaS platform now supports TOTP MFA with backup codes. This document specifies what the server team needs to implement for MFA enrollment in the server UI.

## 1. JWT Claim: `mfa_enrolled`

Every access token now includes an `mfa_enrolled: boolean` claim, set by the Logto Custom JWT script. The server already parses JWT claims for the `roles` field — `mfa_enrolled` works identically.

**Example decoded JWT payload:**
```json
{
  "sub": "user-id-123",
  "roles": ["server:admin"],
  "mfa_enrolled": true,
  "aud": "https://api.cameleer.local",
  "scope": "tenant:manage tenant:view"
}

2. Enforcement

When to enforce

Check whether the tenant requires MFA:

• Endpoint: GET /platform/api/tenant/{slug}/mfa-policy
• Auth: M2M token (same as existing server → SaaS API calls)
• Response: { "mfaRequired": true/false }
• Cache: 5-minute TTL recommended

How to enforce

On authenticated requests, if mfaRequired is true and the JWT mfa_enrolled claim is false:

Response:

HTTP 403
X-Cameleer-Error: APP_MFA_REQUIRED
Content-Type: application/json

{
  "error": "APP_MFA_REQUIRED",
  "code": "mfa_enrollment_required",
  "message": "Your organization requires multi-factor authentication"
}

Exempt paths: MFA enrollment endpoints (below), health checks, public assets.

The server UI should intercept 403 responses with X-Cameleer-Error: APP_MFA_REQUIRED and redirect to the MFA enrollment page.

3. MFA Enrollment API

The server needs to call Logto's Management API to manage MFA for users. Use the existing M2M token for authentication.

Get MFA status

GET https://{logto-endpoint}/api/users/{userId}/mfa-verifications
Authorization: Bearer {m2m_token}

Response: [
  { "id": "ver-123", "type": "Totp", "createdAt": "..." },
  { "id": "ver-456", "type": "BackupCode", "createdAt": "..." }
]

Generate TOTP secret

Generate a 20-byte random secret, Base32-encode it, and create a QR code URI:

otpauth://totp/Cameleer:{userEmail}?secret={base32Secret}&issuer=Cameleer

Show the QR code to the user. After they scan and provide a 6-digit code, verify it server-side using TOTP algorithm (RFC 6238, HMAC-SHA1, 30-second window, ±1 step drift).

Bind TOTP to user

After successful verification:

POST https://{logto-endpoint}/api/users/{userId}/mfa-verifications
Authorization: Bearer {m2m_token}
Content-Type: application/json

{ "type": "Totp", "secret": "{base32Secret}" }

Response: { "type": "Totp", "secret": "...", "secretQrCode": "..." }

Generate backup codes

After TOTP is bound:

POST https://{logto-endpoint}/api/users/{userId}/mfa-verifications
Authorization: Bearer {m2m_token}
Content-Type: application/json

{ "type": "BackupCode" }

Response: { "type": "BackupCode", "codes": ["abc123", "def456", ...] }

Display the 10 codes once. User must acknowledge saving them before dismissing.

Remove MFA (admin action)

DELETE https://{logto-endpoint}/api/users/{userId}/mfa-verifications/{verificationId}
Authorization: Bearer {m2m_token}

Remove all verifications (TOTP + BackupCode) to fully reset MFA for a user.

4. UX Requirements

Enrollment flow

1. User clicks "Set up MFA" in settings
2. Show QR code (200×200px) with the TOTP secret URI
3. User scans with authenticator app
4. User enters 6-digit verification code
5. On success → show 10 backup codes in a 2-column monospace grid
6. "Copy all" and "Download .txt" buttons
7. Checkbox: "I've saved my backup codes" — must be checked before dismissing
8. After dismissal, force token refresh to get mfa_enrolled: true in JWT

Enrolled state

• Show "Authenticator app configured" with green status badge
• "Regenerate backup codes" button
• "Remove MFA" button with confirmation dialog

Backup code fallback (sign-in)

This is handled by the SaaS custom sign-in UI, not the server. No server changes needed for the sign-in flow.

5. Error States

Scenario	Response
User already has TOTP enrolled	422 — "TOTP already configured"
Invalid TOTP code during setup	Show error, let user retry
Backup code already used (sign-in)	Handled by SaaS sign-in UI
All backup codes exhausted	Admin removes MFA via team page
Remove MFA while enforcement active	User will be prompted to re-enroll on next request
