two-factor-authentication-best-practices

Implement two-factor authentication by configuring the twoFactor plugin to manage TOTP authenticator setup, generate secure backup codes, and enforce 2FA after credential verification. This provides a complete server-side and client-side sign-in flow.

2FA state management for trusted devices works by storing secure secrets and backup codes on the server, while the client integration handles device trust to streamline recovery and login experiences without requiring repeated code entry.

Yes, you can send OTP codes via email or SMS for multi-factor authentication. The plugin supports configurable period, digits, and retry policies to customize OTP delivery according to your application requirements.

The best way to set up an authenticator app for 2FA is configuring TOTP-based setup with a specified issuer and optional settings. You can customize digits and period, then wire up the client-side twoFactorClient to verify the workflow.

Yes, this 2FA workflow requires server-side plugin configuration to securely store secrets and backup codes. It also requires client-side setup patterns to ensure seamless integration into existing applications and manage 2FA state.

You need to redirect to a dedicated 2FA page during login immediately after credential verification. This enforces the two-factor authentication step before granting access, ensuring robust login security across server and client configurations.
