Microsoft Authenticator is a free mobile application developed by Microsoft that provides two-factor authentication (2FA) for user accounts. It works by generating a unique six-digit code every 30 seconds that is required to be entered in addition to the user's password when signing into their account on a different device or platform.
Microsoft Authenticator supports a variety of authentication methods, including time-based one-time password (TOTP), which is the default option, and push notification, which sends a notification to the user's mobile device asking them to approve the sign-in attempt.
In addition to providing 2FA for Microsoft accounts, the app can also be used to secure other third-party accounts, such as Google, Facebook, and Amazon, that support TOTP authentication.
Microsoft Authenticator is available for download on both Android and iOS devices, and can also be used on Windows 10 and macOS through the Microsoft Edge browser.
Microsoft Authenticator is a convenient and secure app that allows you to sign in to your online accounts using multi-factor authentication, passwordless, or password autofill. With multi-factor authentication, you enter your password and then provide an additional way to prove your identity, such as approving a notification or entering a one-time password generated by the app. The app supports various accounts, including non-Microsoft accounts like Facebook, Amazon, Dropbox, and more. Passwordless authentication is another feature offered by Microsoft Authenticator. Instead of using a password, you can use your phone to log in to your Microsoft account. After entering your username, you simply approve the notification sent to your phone and use your fingerprint, face ID, or PIN for added security. This two-step verification process grants you access to Microsoft products and services. Additionally, Microsoft Authenticator can autofill passwords for you. By signing in with your personal Microsoft account, you can sync and autofill passwords saved in the app. This feature is protected by multi-factor authentication, requiring your fingerprint, face ID, or PIN for access. You can also import passwords from other password managers like Google Chrome. For work or school accounts, Microsoft Authenticator allows you to register your device and add your organization's account. This enables seamless and secure access to files, emails, and apps without the need to log in multiple times. The app also supports cert-based authentication, which verifies that the sign-in request is coming from a trusted device. Please note that Microsoft Authenticator may request optional access permissions, such as accessibility service, location, camera, and read access to your storage. These permissions are only required for specific features, and you can still use the app for services that do not require them.
