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.

Switching phones and trying to set up Microsoft Authenticator again was a nightmare. While adding two-step verification on my new device, it asks for an authenticator code — from the app I’m still trying to set up. That makes no sense. If your old phone is broken, lost, or wiped, you can easily get locked out with no clear recovery path. The design completely fails in phone-change situations, turning what should be a simple device upgrade into a frustrating lockout experience.

While this was a great feature for Microsoft accounts, it has since become a vector for potential phishing if your email is targeted by means of attempts being made to log in and select a code in the hopes that you accidentally press one of the three numbers available. It got to the point where many attempts a day are being made and I ended up having to remove the authenticator from my account to stop attempts.

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.
