Multi-Factor Authentication Integration

While not strictly password storage, multi-factor authentication (MFA) significantly enhances account security even if passwords are compromised. Time-based One-Time Passwords (TOTP) provide reasonable security with good usability. WebAuthn enables passwordless authentication using hardware security keys or platform authenticators, representing the future of authentication security.

Recovery codes for MFA require the same security considerations as passwords. These codes should be hashed and salted like passwords, with single-use enforcement preventing reuse. Clear communication about recovery code importance and secure storage helps prevent users from losing account access while maintaining security.
