Microsoft is currently working to bring its Windows 10 and Windows 10 Mobile devices in sync, and one of the ways to do that is by developing an app that would allow consumers to use their phones to unlock PCs and log into their desktops.



As noticed by Twitter user @h0x0d, the app is currently in internal beta testing and is called Phone Sign-in. It is essentially a reworked version of the Authenticator app that can allow you to sign into your Microsoft account on a Windows 10 computer instantly, thus adding a new security layer to a PC upgraded to the latest version of the OS.
“The first step towards a world without passwords! After a quick Bluetooth sync, use this app to unlock your Windows 10 computer at work. Just open the app and tap on a nearby computer,” Microsoft explains.
More features to be added soon The store description (the app is indeed published in the store, but you can’t use it just yet since it’s still a limited beta) reveals that Microsoft is already working on some new features, including support for Microsoft account, a sign-in solution for browsers and VPN, one-time passcode generation, and MFA approval through notifications.
At this point, there is no information as to when this application can hit the market, but since it’s already in the store, it’s very clear that the debut could happen soon.
Microsoft hasn’t provided any information regarding this app, but with Windows 10 Mobile also believed to be just around the corner (reports from people with knowledge on the matter indicated that the smartphone OS is scheduled to launch by the end of the month), there’s no doubt that Redmond wants to get it ready as soon as possible.
The company could very well launch the app together with Windows 10 Mobile, but for the moment, we should take this with a pinch of salt and wait for the official release.
