Microsoft Authenticator helps you sign in to your accounts if you've forgotten your password, use two-step verification or multi-factor authentication, or have gone passwordless on your account.

A factor in authentication is a way of confirming your identity when you try to sign in. For example, a password is one kind of factor, it's a thing you know. The three most common kinds of factors are: Something you know - Like a password, or a memorized PIN.

By setting up MFA, you add an extra layer of security to your Microsoft 365 account sign-in. For example, you first enter your password and, when prompted, you also type a dynamically generated verification code provided by an authenticator app or sent to your phone.

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:

Manage your two-factor verification method and settings. Turning two-step verification on or off for your Microsoft account. Set up password reset verification for a work or school account. Install and use the Microsoft Authenticator app.
