A beta version of a new universal Microsoft Authenticator app has popped up in the Windows Store. The app will allow users to unlock their PC from their phone over Bluetooth.
The app currently supports Remote NGC and lets you add ADD accounts. Future versions will include support for Microsoft account, a sign in solution for browsers and VPN, one-time passcode generation, and MFA approval through notifications.
The app is currently only intended for internal testing purposes, but I expect will not take too long to roll out.
See it in the store here.
