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.

    When I try to log into my outlook email it asks me to tap the code in the Authenticator but when I open the Authenticator it opens with a different number. I entered my outlook info in the Authenticator and it doesn’t work

    By AaMir-s
    Plz add Touch ID or Passcode before opening the app.
  • Works alright, would love Watch compatibility

    By forkies
    Will support for Apple Watch be coming soon?
  • Saved me from hackers

    By MsDowser
    Debating on getting this? I did for a long time as I had two step verification. Got this and realized hackers in Romania, Thailand, Korea and more had been using my email address. Who knows what else they done around the globe? Now their sign-in attempts on my email account name are all rejected.
  • Potentially disastrous

    By perkedel
    App works great, but one major problem is that it doesn’t allow its data to be backed up to iCloud/encrypted iTunes back up. So if you do a restore, you lose all your 2FA keys even though all your other apps and its settings are restored, except this one. It’s a problem where you can get locked out of all your accounts. Google Authenticator does not have this problem, have switched to it today because of that massive problem I encountered with missing keys after a restore from backup. I hope the devs are listening!
  • Never had a problem

    By Brian dead riff
    I split my keys between a few apps, and this one has the least number of issues, so far.
  • Where’s facial recognition support?

    By Buddhastyle
    Never had a problem with this app until I bought the iPhone X. Now I need to use my pin because the device has no fingerprint option and the app doesn’t support facial recognition (which is apparently more secure). Please add. Otherwise, this app works great!
  • Takes a lot if tries to make the notification appear.

    By A. C. I
    I have tried few times, but didn't get anything. Then decided to turn off wifi and see if on cellular data the notification would go through and it did. WiFi has an excellent internet connection, so I don't really know what is causing this notification delay or the multiple tries.
  • Won’t download
