U2 Secured Authenticator is a multi-factor authentication platform and mobile app for businesses and developers. Applications, Linux servers, Windows computers and WordPress sites send a push to the app, and the user confirms the sign-in by tapping the number shown on screen and using Face ID or a fingerprint. SDKs for Node, browser JavaScript, Python, Go and PHP add the same approval to custom applications, with webhooks, custom branding per app, a lockout and new-device policy engine and audit log export on every plan. For Linux, one package protects SSH, sudo and the Ubuntu desktop. For Windows, one MSI protects sign-in, unlock and Remote Desktop for local accounts. When a machine cannot reach the service, a time-based code from the app or a one-time backup code is checked on the machine itself, and registered machines report those sign-ins to the developer portal when they are back online. The app also holds time-based codes for other sites and stores passkeys. Developer plans are a flat monthly price per account rather than per user, and codes are not metered on any plan.
