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.
To better protect Authenticator, app lock is now enabled by default if you have a passcode or biometric set up on your device.

Grate Authenticator App
I like functionality of the app and the backup feature is a plus. It was really annoying redoing 2fa when I had to restore my phone.
Good for recovery
I would use this for things I would never want to lose, but technically speaking, it is somewhat less secure & private than say Authy since it can be more easily recovered.
The good thing is, you can use more than one authentication application, for different purposes/accounts.
Causes phone to run very hot.
Whenever I have to use this and then leave it running in the background it causes my phone to excessively heat up and drains the battery. If I remember to close the app and this doesn’t happen.
