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.

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.
NEED DEVELOPER RESPONSE - Locked of all accounts
After upgrading to a new iPhone today, I restored everything from a backup earlier in the day. After installing everything I begin to login to several different accounts like discord, Twitter etc. I didn’t get very far until I got the request to confirm my identity via my Authenticator app. I opened my app to find NOTHING. All of my accounts were gone. I click “begin backup” and get the message that I don’t have a backup on my iCloud account, the same one I had been using for years. I’m completely at a loss. I’ve been frantically trying to contact support from Azure to Microsoft and haven’t found anyone who can or would be willing to help me. I have no idea what to do - this is an atrocious, horrific flaw with this app and I would never have downloaded it if I knew this could possibly happen. I desperately need someone to reach out to me to help correct this issue.
Good app. Using it for years
My company requires us to use 2FA. I liked this one because the Tap to authenticate is very easy to use (It’s integrated with O365 too). No codes to type in. The Watch app makes life really easy - it pops up and I Tap my wrist and I’m in.
4 stars because 2FA can be a pita. ESP on password change day. Every MS product makes me authenticate individually. Office, OneDrive, Teams, Windows. Ugh. At least it just a tap.
I use it for home too. Except on my personal laptop. Why? Because 2FA is a pita at night. Having to go downstairs to find my phone just to login. I just want to look something up real quick but the 30day trust has expired and needs to be renewed. I grow tired of it in my house. Usually my iPad is nearer :-)
