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.



  • Worthless

    Microsoft authenticator app would be much more useful if Microsoft used it for anything. Unfortunately Microsoft does not use their authenticator app for signing into Microsoft accounts apps applications programs computers. But good job shooting yourself in the foot once again Microsoft.

  • On Apple Watch

    This tools really helped me a lot tell now but I have something to say about it’s functional on my watch. First I access my account then as usual it ask for my approval this step appears in my watch then the second step nothing happened it’s show the logo of the app and some dots around it and something like loading “unfortunately I can’t send attached image” so overall I like it and I used almost delay. Thanks Microsoft.
  • Works great, unless you need the recovery option

    Recovery fails
  • So much easier and faster

    Just takes the multiple steps of security steps by using the app is great. Especially if you make your accounts a little to secure Authenticator just helps you add encryption for more security but easier for us users.
  • Very poor app

    By WGCoff
    The app works great at displaying codes but if you need it to authenticate Outlook, good luck.
  • Never fails

    Hi there
  • Terrible App on iOS

    By MerrilM
    I have had nothing but trouble with this app. It is very unreliable, and causes me to not be able to log in to my microsoft account. Microsoft need to enable another form of two-step authentication like a simple text message to my mobile phone. It would so much easier than using this terrible app.
