📄 Description

Summary

  • add allowPasswordless to two-factor management so passwordless users can enable/disable 2FA, fetch TOTP URIs, and regenerate backup codes
  • preserve the password requirement for users with credential accounts
  • expand tests for passwordless flows and update docs to list supported passwordless methods explicitly

Rationale

Passwordless sign-in methods (passkeys, magic links, email OTP, OAuth/social, anonymous) cannot provide a password, but they still benefit from 2FA. This change enables 2FA management for those users while maintaining the existing password gate for credential accounts.

Summary by cubic

Adds passwordless 2FA management so users without a credential (password) account can enable/disable 2FA, fetch TOTP URIs, and regenerate backup codes without a password. Credential users still must provide a password; default behavior is unchanged.

  • New Features

    • Added allowPasswordless to twoFactor, TOTP, and backup codes (default false); top-level option cascades to sub-features unless overridden.
    • Endpoints accept optional password when allowed: enableTwoFactor, disableTwoFactor, getTOTPURI, generateBackupCodes.
    • New shouldRequirePassword utility enforces password for credential accounts and when allowPasswordless is off.
    • Updated docs to mark password as optional for passwordless users and added tests for anonymous flows and credential enforcement.

  • Migration

    • No changes needed by default.
    • To enable for passwordless users: twoFactor({ allowPasswordless: true }) or set per-feature options.
    • Clients may omit password only for users without a credential account; keep sending password for credential users.

Written for commit 4fc867aa55. Summary will update on new commits.
