Microsoft Phone sign-in app to unlock Windows 10 PC without a password
Microsoft has quietly developing an app on the Windows Store called the Phone Sign-in Beta. The app will allow a user to unlock a PC without the need to type in a password, but by just tapping on the PC in the app. The app was spotted at the Windows Store. Microsoft Phone sign-in app can be downloaded by any device running Windows 10 Mobile and will connect via Bluetooth to unlock a PC as well. It works like a two step-authentication process, letting you use a personal device (that hopefully has a password) to unlock a known PC, that was previously paired using the Microsoft Phone sign-in app.
All the user needs to do is to tap on the PC in the app and the PC unlocks, reducing the need to type in a password or even smile at the camera using Windows Hello. According to the description, Microsoft’s intended use for this app and authentication procedure is for office purposes. Also, the description for the app tell us that the company plans to add some more features like support for Microsoft accounts, a sign-in solution for browsers and VPN, one-time pass-code generation, and MFA approval through notifications. To signing in directly into your account on your home PC would also make the Microsoft Phone sign-in app really handy especially if you have a long password to remember and type down.

The Windows Store listing warns that the Microsoft Phone sign-in app is only intended for internal testing purposes. The app is still in a beta testing phase. It also hints that the app is the first step towards a world without passwords. At the moment, the Microsoft Phone sign-in app is only for Windows 10 mobile devices. It uses a Bluetooth connection to unlock a Windows 10 PC. Using this app the unlocking of a Windows 10 computer would just require a tap from a phone already paired with the computer.
