Microsoft Authenticator is an authentication method developed by Google that uses a time-based one-time-passcode (TOTP) in order to verify users' identities. It is often used as one of the multi-factor authentication (MFA) methods along with others in order to secure the login process into a service. Authentication using this method requires the Microsoft Authenticator app. After the users have provided valid login credentials, the service asks them for the 6-digit TOTP from the app. The users then have to run the app to obtain the TOTP and enter it in the service, and verify their identity.

Empowering Active Directory domain users with self-service password reset can benefit an organization in more ways than one.

• Users need not wait for admin intervention and can have seamless access to their machines.
• The help-desk admin will not be tasked with hundreds of password reset requests and can instead attend to other crucial tasks.

However, providing users with the ability to reset their passwords can be risky if proper security measures are not put in place. Since users won't have to provide any old credentials, it is important to verify their identities before they can reset their passwords. Using a multi-factor authentication (MFA) method like Microsoft Authenticator is a fail-safe way to authenticate them for Active Directory domain password resets.

ADSelfService Plus, an identity security solution, offers a self-service password reset and account unlock feature that is secured by MFA. The solution supports up to 19 methods of MFA including Google Authenticator, biometrics, and YubiKey Authenticator to verify users' identities during
