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.
We're always working on new features, bug fixes, and performance improvements. Make sure you stay updated with the latest version for the best authentication experience.
Ratings and Reviews
This app is great
So a few months ago I got my Xbox account hacked and I was really sad about it because I had lost a lot. Including my games ect. But then I found out the hacker stole my email and put it in this app because at the time I didn’t have this app. So that was a good lesson for me to use this app always and it’s absolutely fantastic because I have a lot of emails like work, school, and gaming of course but I feel like all my emails are super secure also I like the fact that when trying to log into another site with your email you have to get permission from the Authenticator app before you can do anything so if someone gets ahold of your email then they can’t log in at all.
Watch app is not up to park with Phone app
I don't believe I've ever been able to get the Authenticator app to work properly with push notifications on the Apple Watch. I get the notification on the Watch just fine. I approve it, select the correct number shown on the screen, then it thinks for a second and says "Something went wrong." I pull out my phone and perform the same steps and it works great, Face ID and all that goodness on the phone. This issue has persisted two different phones, multiple app updates, and different IOS builds. Not sure if MS will ever fix it but I'll hold out hope for them to fix the otherwise great service.
Love it for how it works as a remote Authenticator for OneDrive & Outlook, and especially for work to authenticate with TouchID when logging in to work resources.
BUT - really frustrated by how you lose 2 factor or step linkage to services when you have to restore your iPhone (either from having to erase or moving to a new iPhone) and now I’ve lost login access to some services I used it with for 2 factor. One in particular doesn’t even offer email temporary recovery so I have to completely wipe my settings and information to re-establish access.
