Passwordless Authentication

Email OTP authentication in Account UI

Account UI supports passwordless authentication via email OTP.

Email OTP

When ENABLE_EMAIL_OTP=true:

  • Users enter their email address
  • A one-time password is sent via email
  • User enters the OTP code to authenticate

The sign-in email contains the six-digit code only — no magic-link companion. Mail-client URL prefetching burns single-use links, so a code the user types is the reliable path.

Account UI does not offer a magic-link sign-in flow. The magicLink Better Auth plugin is still available at the API level (see Auth Plugins) for apps that build their own sign-in UI, but the bundled Account SPA is OTP-only by design.
