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.



  • Doesn’t work for me.

    Complete waste
  • Horrible

    If your changing your phone number and don’t already have an existing Microsoft Authenticator setup on another device then you will not be able to proceed. End of story. Horrible...
  • Scam

    By hitthegas1
    I have never heard of this app until it popped up a message on my device stating that it was about to install itself from the App Store. This message appeared multiple time per day for the past five months despite hitting cancel every time. I even tried allowing it to install once and then I went in and removed my information that it somehow already had without me entering it followed by quickly deleting the app. That’s pretty fishy right? Smells like a scam to me!
  • Do NOT use this app - IMPOSSIBLE to UNINSTALL

    By lafapilot
    This app will be on your iPhone FOREVER. It is not possible to uninstall it and it will notify you every couple hours to reinstall it.
  • Needs more account icons

  • Stupid.

    By Skybugloves
    This app never notifies me if I’m trying to sign in so I can’t sign into my freaking school account. This is all dumb and I hope literally no other company or school requires you to download this awful app. Which by the way, if you have trouble with it, the people who made the app do not help you at all. You have to go to whoever made you get the stupid app. It’s all dumb. And it doesn’t work. Even if I manually generate a code, it just doesn’t accept it.
  • Updates with garbage release note

    By Lt Gizmo
    Look at the update history and we would see the same release notes that tells the user absolutely nothing. How did this kind of behavior gets pass review is total mystery.
  • Excellent app, but…

    By Abraham Isaac Duran
    Why don’t you add an option so one has to use Touch ID in order to open the app and access the codes?
  • Thank you

    Thank you for continually trying to invent ways of increasing account security.
  • Solid. But needs spit-polish

    By CyberData4
    The core functionality of the app is rock solid. It works. Every time. Not one crash. But my problem is all this time I see no spit polish with some nice to have features. Example 1: Now, this is petty. Tom Petty. But for accounts that don't automatically pull in an avatar image ID like the option to set it myself. When I click edit I should be able to click each image and set it from photos. Example 2: For an app that provides security why can't I set a password or touched for opening the app? Like everything else I can enable this with the understanding that it's my responsibility to secure said password to access my app. This way no one can snatched my phone when it's on but unlocked at my desk and I'm in the restroom. It's the little quality of life things that are missing that could really set this app apart from the competition. That being said I trust MS with my data more than Google so I'll keep this. Good job. But please consider these changes.
