Two Factor Authentication

Microsoft 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.

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.
