AuthLatch

AuthLatch helps site owners replace routine password logins with secure passwordless access.

Key features:

• One-time magic links requested by username or email, with expiry and one-use tokens.
• Passkey login using WebAuthn/FIDO2.
• Self-service AuthLatch sidebar page for selected user roles.
• Users can add, revoke, and name their own passkeys.
• Users can send a magic login link to their own account email.
• Per-role passkey access and per-user passkey limits.
• Branded responsive login screen with method tabs for magic links, passkeys, and password fallback.
• Single active session control.
• Admin-generated login links with optional IP binding and auto logout.
• Admin-scoped login links that can block selected admin menus for that session.
• Built-in SMTP settings for hosts where PHP mail delivery is disabled.
• Audit log for important authentication events.
• RTL-friendly login UI.

AuthLatch stores magic-link validators as hashes, verifies passkeys server-side, and uses WordPress capabilities, nonces, sanitization, and escaping throughout the admin interface.

Password fallback

1. Keep Username/password login enabled if normal WordPress login should remain available.
2. Keep admin password fallback enabled if administrators should still be able to log in with a password when password login is otherwise disabled.

Privacy

AuthLatch stores authentication-related records in the WordPress database, including hashed magic-link tokens, passkey public-key data, hashed IP values for audit and optional IP binding, and configuration settings. AuthLatch does not store plaintext magic-link validators. SMTP passwords are encrypted with WordPress salts before storage.

Third-Party Libraries

AuthLatch includes the MIT-licensed lbuchs/WebAuthn library for WebAuthn/FIDO2 server-side verification.
