Ever since it's release, the Microsoft Authenticator app has been a great way for you to quickly and securely verify your identity online for all of your accounts. Microsoft recently pushed out an update for the beta app on iOS and Android, and it adds support for a phone sign in feature.
Overall, the update brings the newest version number on iOS to version 5.0.0, and on Android to version 6.0.2. According to Neowin, the updates enables a "use an app instead" function upon login, which will give you a push notification on your phone or smart watch. After you interact with this notification, you can then enter a pin or fingerprint to login, or complete a challenge which gives you a number to repeat that was seen from within the app. To enjoy the feature, however, you must make sure that you already have a password, fingerprint, or pin on your device, and then choose "enable phone sign-in" from within the app.
So, if you're currently using this app, be sure to head over to your app store now and check for an update! Even if you're not using the app, you may check it via the links below. As always, let us know what you think of the latest update by dropping us a comment.
