The app is available for Android, iOS and Windows Phone devices, but a new Microsoft Authenticator app feature that bypasses Microsoft account passwords, called "phone sign-in for Microsoft accounts", was only added to the apps for the Android and iOS mobile platforms.

In some cases the app will produce an eight-digit password for the authentication.
