Demo: Implement Multi-Factor Authentication (MFA)

Overview

Enhance application security by implementing multi-factor authentication for user accounts.

Business Value

  • 🔒 Reduces account compromise risk by 99.9%
  • 📊 Meets compliance requirements (SOC2, ISO 27001)
  • 👥 Builds customer trust in our security posture

Technical Requirements

Phase 1: TOTP Implementation

  • Integrate PyOTP library for TOTP generation
  • Add QR code generation for authenticator apps
  • Create backup codes system
  • Update user model with MFA fields

Phase 2: User Experience

  • Design MFA enrollment flow
  • Create MFA verification page
  • Implement "Remember this device" option
  • Add MFA status to user profile

Phase 3: Administration

  • Admin override capabilities
  • MFA enforcement policies
  • Audit logging for MFA events
  • Recovery procedures

Security Considerations

  • Store recovery codes hashed (bcrypt)
  • Rate limit verification attempts
  • Secure session management after MFA
  • Time-window validation for TOTP

Acceptance Criteria

  • Users can enable/disable MFA
  • Support for Google Authenticator, Authy, etc.
  • Recovery process without phone access
  • Admin can enforce MFA for specific roles
  • All MFA events logged for audit
  • Performance impact < 100ms
