Passwordless Authentication

Email OTP and magic link authentication in Account UI

Account UI supports passwordless authentication via email OTP and magic links.

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

When ENABLE_MAGIC_LINK=true:

  • Users enter their email address
  • A login link is sent via email
  • Clicking the link authenticates the user

Combo Auth

When both are enabled, Account UI uses the @kardoe/better-auth-combo-auth plugin to combine them into a single flow — the email contains both a clickable link and a code.
