About Microsoft Authenticator
Applies To
Microsoft AuthenticatorMicrosoft Authenticator is a free app that helps you sign in to all your accounts without using a password - just use a fingerprint, face recognition, or a PIN.
You can use Authenticator to sign in to your Microsoft personal, work, school or other accounts.
Note: Starting July 2025, the autofill feature in Authenticator will stop working, and from August 2025, passwords will no longer be accessible in Authenticator. Learn more.
Authenticator can be used three ways:
-
As a way to verify sign-in if you forget your password.
-
As a way to sign in every time, by using a one-time password code to increase account security. This is called two-step verification or multi-factor authentication.
-
As the only way to sign in - just tap an approval on your phone to sign in. This is called going passwordless.
Just follow the three steps to start using Authenticator to sign in.
