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

Garbage. If your company decides to use this, best of luck. And if you get a new phone, I wish you even more luck, because that is absolute hell, trying to get the authenticator to recognize your new phone. There have got to be better ways to secure digital things than this damned app. Also, you won't be able to use it if you lose reception or don't have Wi-Fi, which is a common occurrence in our very large building.

I lost my phone once so was worried about how I would access my account. But the customer service was professional, secure, and COMPLETELY efficient. Solved my problem and got me authenticated pretty quickly and easily and I was SO grateful for that. Because I was expecting it to be a total nightmare. Also, when I called their customer service, a REAL PERSON answered my call, which is almost solely enough to give this app an A+++ rating!

I was forced to install this app. My work email literally wouldn't open until I did. I did not elect to participate in the use of a two-factor authentication system that, based on the reviews available on the website, will inevitably lock me out when I get a new phone, will subject me to endless code loops, and will offer no customer support. Between this and the disabling of Office features if you opt out of AI, Microsoft is no longer a company; they are an ongoing hostage negotiation.
