The Microsoft Authenticator app has various features that can help you use your accounts more securely, therefore avoiding threats like compromised and stolen passwords. It also acts as a backup in case you forgot your password, especially for accounts that you didn’t use for a long time.

Your Microsoft account can be used to access Windows, xbox Live, Hotmail, Azure as well as many businesses. So it is important to keep your account secure.

These are four main ways how you can use the Microsoft Authenticator app:

• Two-factor Authentication – In this method, one of the factors is your account’s password. Once you sign in with your username and password, you will need to further approve the sign-in via notification or a unique verification code.

• Code Generation – You can use this app as a code generator when signing in to an app that supports code generation.

• Phone Sign-in – Another version of two-factor authentication where you can sign in without a password. It uses your phone’s verification methods like fingerprint, PIN, and face recognition.

• One-Time Passwords – Aside from two-factor verification, the Microsoft Authenticator app also supports time-based, one-time passwords (TOTP) standards.

If you’re a part of a work or school organization, you might be required to use the Microsoft Authenticator app to gain access to your organization’s documents and other confidential data. A complete setup of this app is required to use as a trusted verification method.
