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.



  • Update app

    By Rp vv
    Awesome but I would like to make a suggestion. Maybe update the app to fit the iOS style like all your other Microsoft apps, having a bottom bar navigation and no hamburger menu. That would be awesome
  • The best app of kind

    By Kkksjjjsjsjsssj
    Thanks to microsoft for making it so good, unlike some other crap like google authenticator.
  • Gather your data by default

    By smartfin
    Be careful, this app has option to gather data about your usage turned on by default. So, you can’t be sure what exactly they are collecting and you must go to setting to turn it off. Beside this, Microsoft use some non standard protocol, so other 2FA apps can’t support it
  • Have not had any luck with this

    By Ellis9983
    Well shortly after I downloaded this app and added accounts to it my phone was reset and now can’t get n any of my important accounts and. The files of my back up codes of course was in the cloud which I thought would be safe ha and even backup to the cloud none of this worked and even tried to start all over and recover like it says on Microsoft support page ✌️💩

  • The App Is Good But Not Amazing

    By Stolen Gold
    It’s ok. I would use it but just wish I could’ve log in to backup my codes. But I do like the fact that I can log in with it’s special 2FA feature for logging in to my Microsoft accounts.
  • Authenticator is easy and solid

    Microsoft got this thing right!
  • Prepare for your iCloud backup to disappear! Read other reviews!

    By Chaunold
    Thanks Microsoft as always. Been using this app for awhile and recently got a new phone. I’ve used iCloud backups before just fine with this app in the past, and it changed this recent time. Now Microsoft Authenticator sees I have no backup and wants to start fresh! Wow! And yes, my iCloud account is not expired and no account changes have been made.
  • Setting up Authenticator

    By phosmo
    It is very confusing what to do with the thirty sec. code, the half minute code, the eight digit code of two four digit numbers
