Features

Email Verification (Stub Implementation)

# Get verification status
GET /api/auth/verify/status
Authorization: Bearer <token>

Response:
{
  "email_verified": false,
  "message": "Email is not verified"
}

# Send verification email (stub)
POST /api/auth/verify/send
Authorization: Bearer <token>

Response:
{
  "message": "Verification email sent (STUB - no actual email sent)",
  "email_sent": true,
  "verification_token": "abc123..."  // For testing
}

# Verify email with token
POST /api/auth/verify/email
Content-Type: application/json

{
  "token": "abc123..."
}

Response:
{
  "message": "Email verified successfully",
  "email_verified": true
}

Note: This is a stub implementation. In production:

• Use an actual email service (SendGrid, AWS SES, etc.)
• Send HTML emails with verification links
• Store tokens securely
• Implement rate limiting
• Add email expiry checks

Account Settings

# Get settings
GET /api/users/me/settings
Authorization: Bearer <token>

Response:
{
  "email": "user@example.com",
  "username": "username",
  "email_verified": true,
  "recovery_enabled": true,
  "email_notifications": true,
  "theme": "light",
  "language": "en",
  "timezone": "UTC"
}

# Update settings
PUT /api/users/me/settings
Authorization: Bearer <token>
Content-Type: application/json

{
  "email_notifications": false,
  "theme": "dark",
  "language": "es",
  "timezone": "America/Argentina/Buenos_Aires"
}

# Change password
POST /api/users/me/change-password
Authorization: Bearer <token>
Content-Type: application/json

{
  "current_password": "CurrentPassword123!",
  "new_password": "NewPassword456!"
}

Response:
{
  "message": "Password changed successfully. Please login again."
}

Security Features:

• Current password required for password change
• All tokens invalidated on password change
• Token version incremented automatically
• User must re-login after password change
