Two-Factor Authentication

Implement two-factor authentication by guiding users through enrolling a second factor and verifying it during login. This process adds an extra verification layer beyond passwords to protect user accounts from unauthorized access.

Supported 2FA methods include TOTP authenticator apps, SMS codes, and security keys. Each method provides a distinct second verification step to confirm user identity during the login process.

You need multi-factor authentication when protecting user accounts from unauthorized access requires more than just a password. It is essential for applications like banking where an extra verification layer confirms user identity securely.

Yes, this two-factor authentication guidance addresses accessibility, performance, and security best practices. It ensures the setup and verification flows for methods like TOTP and security keys remain robust and usable.

TOTP uses an authenticator app to generate time-based codes, while SMS sends codes to a phone. Both serve as a second verification factor, but security keys offer a distinct hardware-based alternative for account protection.

Yes, adding an extra verification layer can be integrated smoothly. The guidance covers setup and verification flows that balance security best practices with accessibility and performance to maintain a usable login experience.
