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.

    By juniortsf
    The restore feature is broken other than that it works just as intended
  • It’s a bunch of garbage!

    By ValdostaDM
    I’ve been trying to load this app and it just keeps endlessly cycling and changing numbers! All I wanted to do was change my password because the system said it didn’t recognize it and it was making me ask for and type in all these ridiculous codes. This is hell on earth!!!!

  • MS launches yet another piece ‘o poo

    By Radio Recording Guy9
    It’s like these guys never bothered using their own apps. JUST TO SET UP A PIN LOGIN FOR MY LAPTOP, I had to give MS my mobile number (that will never happen), or authenticate through their app. 1) the app gives me the option of turning off notifications, so I turn them off. 2) it directs me type in a code from the app. But then it doesn’t work because notifications must be turned on. 3) I turn on notifications and try for several minutes to get the code accepted. Error message: you have used this code before. No further instructions. 4) I step back and generate a new code and try to submit this. Nothing happens, no message, no instructions. 5) Finally I give up and supply my work phone for authentication. MS must have a phone. 6) Finally, after ten minutes of struggle, my laptop is authenticated for use of a PIN for log in. Is there anyone else having a problem with MS’ crappy software? There is no evidence they have ever tested this app. What an utter piece of crap. MS should be ashamed.
  • Worst. Do not turn this on.

    By Hherrig
    Got a new phone and something didn’t transfer with the Authenticator. I have been locked out of my email for over 60 days & counting and this has been a nightmare. When will I ever get access to my email again.
  • Newest version deletes ALL accounts upon re-launch

    Unbelievable. Did you not test this at all?!?!?
