About this app

Two factor authentication (2FA or TFA) is easy, convenient, and secure when you use Microsoft Authenticator. Use your phone, not your password, to log into your Microsoft account. Just 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’ve signed in with two factor authentication (2FA or TFA), 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 (MFA) even if you still use a password, by providing a second layer of security after you type your password. When logging in with two factor authentication (2FA or TFA), 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 one time password (OTP) generated by the app. The one time passwords (OTP codes) have a 30 second timer counting down. This timer is so you never have to use the same time based one time password (TOTP) twice and you don’t have to remember the number. The one time password (OTP) doesn’t require you to be connected to a network, and it won’t drain your battery.

You can add multiple accounts to your app, including non-Microsoft accounts like LinkedIn, Github, Amazon, Dropbox, Google, Facebook, and more. Since the app supports the industry standard for time based one time passwords (TOTP), you can secure all your online accounts. Simply enable two factor authentication (2FA or TFA) on all your accounts. Then, when you sign in, you’ll provide your username and password as usual. Finally, you’ll enter the one time password (OTP) provided by the Microsoft Authenticator 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.

Ratings and reviews

BE VERY CAREFUL with this app. It doesn't save your data like a normal app would. If you ever reinstall this app, make sure you go slowly and read every single direction, every step of the way before proceeding each step. I reset my phone occasionally to clean it out. When reinstalling this app, I permanently deleted all of my 2FA accounts, doing what it was prompting me to do, because I missed a small notice on the bottom of the log-in process.

I have to use the authenticator app for work too and it doesn't work well. I have tried multiple times and nothing. I have even tried several things like turning my notifications on, calling the helpdesk (not through Microsoft), trying to log in, etc. nothing has worked. As for my personal account, I haven't had any issues at all. Infact I would recommend it even though I don't really know what this app is for.

Manually editing passwords does not work. I keep winding up with my passwords incorrect in this app and in my Edge browser. Turns out it's because when I change the password for something on my phone, and then go manually update it in this app, the change does not save. I then end up with the password being saved nowhere, and needing to reset it again.
