An authenticator app provides an additional layer of security that is more than just a username and password.
Let’s start with the basics…
Authentication is the process a user goes through to validate who they are by way of logging basic identification details such as an email address or username followed by a password. To protect high-valued accounts, passwords aren’t always enough.
Multi-factor authentication (MFA) or two-factor authentication (2FA) provides an additional layer of security to avoid phishing. Passwords can be forgotten or compromised and MFA or 2FA helps access accounts more securely making it harder for other people to break in.
There are numerous factors of multi-factor authentication:
The combination of two or all these types creates the multi-factor authentication method, and this is where Microsoft, Google, or any other authenticator app comes into play.

Both app’s interface might look the same but there are a few features that differentiate them.
It both generates time-based 6 or 8-digit codes during the verification process when you sign in on your online accounts and the apps work for mobile and tablet devices running on iOS and Android.
Aside from Microsoft accounts or Google accounts, it can also be used as an authenticator for other products such as GitHub, Dropbox, Facebook, or interchangeably.
Microsoft list the following ways to use Microsoft Authenticator app on its documentation:
Two-factor verification. The standard verification method, where one of the factors is your password. After you sign-in using your username and password, you can either approve a notification or enter a provided verification code.Phone sign-in. A version of two-factor verification that lets you sign-in without requiring a password, using your username and your mobile device with your fingerprint, face, or PIN.Code generation. As a code generator for any other accounts that support authenticator apps.
No matter the app, it is vital to implement multi-factor authentication to prove a user’s identity and protect individuals from data theft.
