What 2FA delivery methods does Better Auth support?▼

Better Auth supports TOTP (Time-based One-Time Password) authenticator apps and OTP delivery via email or SMS. You need to configure additional email or SMS libraries to handle the OTP code delivery for multi-factor authentication.

Can I manage backup codes and trusted devices with Better Auth 2FA?▼

Yes, Better Auth's twoFactor plugin handles backup codes for account recovery and allows you to manage trusted devices. This provides a streamlined sign-in experience for multi-factor authentication without compromising security.

Does Better Auth require additional libraries for SMS OTP delivery?▼

Yes, Better Auth requires additional libraries for SMS or email delivery when implementing OTP-based two-factor authentication. You must integrate external delivery services to send the one-time passwords to users.

When should I use TOTP instead of email OTP for multi-factor authentication?▼

Use TOTP authenticator apps for high-security environments requiring offline verification, and use email or SMS OTP delivery when you need accessible multi-factor authentication without requiring users to install an authenticator application.
