Microsoft is one of many companies hard at work on developing a successor to the modern password. The Redmond-based firm already offers a number of alternative log-in methods in Windows 10 including setting up a PIN and using a picture password.
Now, Microsoft is quietly beta testing another approach that relies on your nearby smartphone.
A new app in the Microsoft Store called Phone Sign-in Beta is a beta version of the Authenticator app described as the first step towards a world without passwords.
