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.

    I tried to love this app. I liked it clean and simple interface. I liked that it connected easily to my outlook account. I waited forever for a watch app. After a couple version testing the beta with no luck I think I’m in the clear once 12 comes out.. nope. Still won’t connect. Deleted Authenticator and moved over to OTP Auth where the watch app works flawlessly.
  • Let me go!

    By MaureenNash
    I left Microsoft, but the app keeps trying to force-install at least 4-5 times a day. My alias should be inactive now, and I removed the account before uninstalling. I just want it to stop! 😡
  • Watch app completely unstable

    By Vine301
    I can’t get the watch app to work. Either tells me it cannot communicate with my phone or it says that the account is not on my watch. Reinstalling and restarting doesn't work either. This needs a lot more work.
  • Crap

    App is crap
  • Apple Watch support useless

    Did they even test it? Timed out twice while setting up. After it worked on the third time, it does absolutely nothing. All the notifications go to the phone, like the watch doesn’t exist. Typical Microsoft. A bare minimum solution with zero real QA.
  • Doesn’t Work

    By vegastune
    The codes it provides do not work. I am locked out of my email.
  • Please authenticate > enter code > FAIL

    It makes you question your own highly cherished IQ. Worthless apps of this sort needs to be phased out.
  • Can’t log in

    By Mayerrocks
    It’s that simple. Trying to login to group me. Nothing.
  • Lacking Face ID to unlock the app

    Lacking Face ID to unlock the app.
  • Breaks OneDrive login

    By thegreatestajax
    Having this app installed along side OneDrive prevents OneDrive from having persistent log in, stopping camera upload and removing OneDrive from the Files app.
