- Add security notification email after password reset (warns MFA
was not required, recommends enabling it)
- Use distinct APP_MFA_REQUIRED error code + X-Cameleer-Error header
for MFA enforcement 403s to avoid collision with generic access denied
- Make backup code fallback prominent in MFA verification UI (visible
secondary action, not a subtle link)
