Sign in is easy, convenient, and secure when you use Microsoft Authenticator. Use your phone, not your password, to log into your Microsoft account. You simply have to enter your username, then approve the notification sent to your phone. Your fingerprint, face ID, or PIN will provide a second layer of security in this two step verification process. After, you'll have access to all your Microsoft products and services, such as Outlook, OneDrive, Office, and more.

Microsoft Authenticator also supports multi factor authentication for work, school, and non-Microsoft accounts. The app provides a second layer of security after your password. When logging in, you'll enter your password, and then you'll be asked for an additional way to prove it's really you. Either approve the notification sent to the Microsoft Authenticator, or enter the verification code generated by the app. 

Sometimes your work or school might ask you to install the Microsoft Authenticator when accessing certain files, emails, or apps. You will need to register your device to your organization through the app and add your work or school account. Microsoft Authenticator also supports cert-based authentication by issuing a certificate on your device. This will let your organization know that the sign-in request is coming from a trusted device and help you seamlessly and securely access additional Microsoft apps and services without needing to log into each. Because Microsoft Authenticator supports single sign-on, once you have proven your identity once, you will not need to log in again to other Microsoft apps on your device.

What’s New

Version 6.4.22

To better protect Authenticator, app lock is now enabled by default if you have a passcode or biometric set up on your device.

Best app with problems on new iOS

Hi I love your app. Especially notifications and opportunity to confirm authentications on watch. But after last iOS and watchOS update the watch part of the app is not working. It doesn’t see any account from iPhone app so notifications are not working to. I was doing factory reset after iOS update for phone and watch. And recover data in your app from menu of the app. App is working great only watch part stopped work.
I hope you can fix it soon.
Good luck and keep doing best authorization app. 👍

You really need to add Touch ID, because it can be so much safer.... (otherwise 5/5 stars...)
