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.



  • Overall good, but needs a widget and open faster

    By ryan.littleking
    The app is formatted nicely and the push notifications for instant approval for logging into Microsoft accounts are cool. However, I’d love to see an iOS Widget made for quicker access and for the app to launch faster. Google Authenticator opens practically in an instant.
  • Great on iPhone Watch app is a bust

    By EdLewis2
    Authenticator works very well on iPhone. It has been solid and reliable where i use it on a number of accounts. 5 stars. I was excited to hear a Apple Watch version came out. That is a complete bust, not working at all. Zero stars. The Watch app does nothing but declare that an account can be set up. Fiddling with it for a half hour gave the proclamation ‘setup successful’. Still not producing codes like it should I discovered to my dismay that the iPhone version crashed and had to be removed and reinstalled. Suggestion: take the Watch app off the store until it is properly documented and can be made to work. 5 stars for iPhone app, 0 for watch gives an average of 2.5 or 3.
  • Does not explain itself; found useless

    By Ttg85
    Introduction leads nowhere
  • Watch Authenticator still not working

    By RL1
    After latest update, the watch portion of the app is still broken
  • What an awful app -10000000000 stars

    I’ve tried to get this to work for the past 4 days. It just doesn’t work. It’s not that it’s slow, or that it isn’t secure it just doesn’t do.... anything. The two most common messages I get are “something went wrong, please try again later” and “let’s try it out” and then I wait, and wait, and wait... oh there!!.... Nope... still waiting. 4 days later. Maybe if there were instructions. That would be a novel idea. Or if the app set up by taking you through the proper steps.. OHHH that’s right! I’ve already tried that too. And... you guessed it.... it doesn’t work.
  • Redesign?

    By Rp vv
    Great app, what i would like to see is a redesign, make it look like Outlook app, cleaner icons and maybe icons on the bottom bar, they should fit. This looks to much like Android version. Otherwise great app!
  • App Lock

    By Python922
    For a security purpose app, it’s shocking that it doesn’t have an lock to enter the app. Other functions are good. Apple Watch app usually fails.
  • Face ID

    By ashok.kandikanti
    Common sense this app needs Face ID enabled
  • Fustercluck

    By jbrandonf
    I tried to love this app. I liked it clean and simple interface. I liked that it connected easily to my outlook account. I waited forever for a watch app. After a couple version testing the beta with no luck I think I’m in the clear once 12 comes out.. nope. Still won’t connect. Deleted Authenticator and moved over to OTP Auth where the watch app works flawlessly.
  • Let me go!

    By MaureenNash
    I left Microsoft, but the app keeps trying to force-install at least 4-5 times a day. My alias should be inactive now, and I removed the account before uninstalling. I just want it to stop! 😡
