If you think typing passwords are already a thing of the past and you prefer those fingerprint recognition systems or retina authentication procedures, then the latest one from Microsoft is a more convenient yet subtle approach in unlocking your devices. The Redmond-based company has quietly released the Phone Sign-in app for the Windows 10 mobile platform that, as its name suggests, can sign users in to their Windows 10 computers with a single tap.

“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,” reads the description of the app.

A Twitter user with the handle “WalkingCat” discovered the existence of the Phone Sign-in Beta app. To put it simply, the app will allow users with Windows 10 Mobile phones to unlock their computers through Bluetooth connection with just a single tap from a long list of devices to unlock it.

Microsoft is hard at work in bringing new and ingenious ways on how users can sign in to their Windows 10 devices without even the need for a password. If you still remember, Windows Hello is a feature in the platform that lets users unlock their PCs using cameras and fingerprint readers.

At the moment, the app is only exclusive for Windows 10 Mobile smartphones since it can only be downloaded via the Microsoft Store. With that said, the company may be looking to make its users go with Microsoft’s ecosystem.

The Phone Sign-in app is still in its beta testing phase, so we can likely expect that Microsoft will be adding more features into its latest unlocking app. Hopefully, Android and iOS support will come along the way. After all, the company has been bringing its apps in several major platforms as of late.
