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 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.

  1. Get the app.

  2. Add your account.

  3. Learn how to sign in.
