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.

  • Needs Better Apple Watch Support

    By Alapacho
    Mostly everything about it is great, however it’d be ideal to see the 30-second OTPs on the Apple Watch so I don’t have to keep reaching for my phone.
  • Locked out. Credentials don’t restore

    By cpragman
    I have to use this app for work’s VPN. I frequently backup my phone to iTunes with encrypted backup so all my account setting will be preserved. After iPhone restore from an iTunes backup, this app has lost ALL my information. I can no longer login to work via VPN, until I am physically back in the office to reinstall a new security key while on the work LAN. If I had been using this app for online accounts like Twitter, I would have been totally locked out.
  • Lost all keys

    Just like others have said. Lost all codes and iCloud backup didn’t work even though it was enabled. Make sure you keep your old phone to setup the new one.
  • Regression on iOS 13

    By GalacticViceroy
    It notifies me of authentication requests but rarely shows the fingerprint UI to allow me to actually complete authentication.
  • Add QR for Third-Party Additions

    By Senator Blair
    2+ stars for making an otherwise perfect UX
  • You may get locked out of your accounts

    By Squirlnutz
    I used this to sign in conveniently while setting up 3 new devices a few months ago. I have a new windows10 machine and instead of signing in as normal I am being forced to use this Authenticator app that does not keep records. I opened the app and I am having to setup as if it is brand new however, because it did not keep my information I can’t sign in to the new machine, Microsoft account or any thing else because I am being forced to use an app that i can’t use.... I use several different machines mainly Linux but enjoy the convenience of Microsoft.

    Lost all my codes twice now because the backup feature doesn’t work. No support contact that can help.
  • NEED DEVELOPER RESPONSE - Locked of all accounts

    By JHesidenz
    After upgrading to a new iPhone today, I restored everything from a backup earlier in the day. After installing everything I begin to login to several different accounts like discord, Twitter etc. I didn’t get very far until I got the request to confirm my identity via my Authenticator app. I opened my app to find NOTHING. All of my accounts were gone. I click “begin backup” and get the message that I don’t have a backup on my iCloud account, the same one I had been using for years. I’m completely at a loss. I’ve been frantically trying to contact support from Azure to Microsoft and haven’t found anyone who can or would be willing to help me. I have no idea what to do - this is an atrocious, horrific flaw with this app and I would never have downloaded it if I knew this could possibly happen. I desperately need someone to reach out to me to help correct this issue.
