FAQPage Schema
How do I implement multi-factor authentication for user login flows?▼

Multi-factor authentication is implemented by configuring the twoFactor plugin to manage TOTP, email/SMS OTP, and backup codes, prompting users for a verification code after their initial password entry during the sign-in process.

What is the best way to set up TOTP and backup codes for account security?▼

The best way to set up TOTP and backup codes is to use a dedicated MFA lifecycle manager that guides users through authenticator app configuration and generates single-use backup codes for secure account recovery.

How does trusted device management work with 2FA verification?▼

Trusted device management in 2FA verification allows users to mark specific devices as safe, skipping subsequent MFA prompts on those devices to provide a smoother and faster login experience.

Can I use email and SMS OTP alongside TOTP authenticator apps for MFA?▼

Yes, you can use email and SMS OTP alongside TOTP authenticator apps, as the multi-factor authentication setup supports all three methods to secure user accounts and provide flexible verification options.

How do I handle account recovery when users lose access to their 2FA methods?▼

Account recovery when users lose 2FA access is handled through single-use backup codes provisioned during setup, allowing users to securely regain entry and manage their multi-factor authentication settings.
