Microsoft Authenticator is an app used for two-factor authentication (TFA), which helps secure your accounts. It competes with apps like Google Authenticator and Authy. You might use it when updating your Microsoft account or turning on TFA. It’s available for download on the Google Play Store or Apple App Store.
The app lets you sign in to your Microsoft account without a password. It also supports multiple accounts and works with non-Microsoft websites and services.
The app generates a 6 or 8-digit code every 30-60 seconds. When logging in, you’ll be asked for the two-factor code. Open the Microsoft Authenticator app to get the code.
For Microsoft accounts, you can log in without a password using codes or push notifications, plus a secondary phone authentication (like fingerprint or PIN). For other accounts (e.g., Facebook, Google), you must log in with your username and password before entering the code.
The app works with any website using the TOTP (time-based one-time password) standard, generating codes for you to use. Most apps support this, except some banking apps.
