Microsoft Authenticator offers a user-friendly and secure way to sign in to all your online accounts, using multi-factor authentication, passwordless, or password autofill. The app also allows for additional account management options for Microsoft personal, work, or school accounts.
For added security, multi-factor authentication provides a second layer of verification. After entering your password, you will need to provide an additional form of identification through the app, such as approving a notification or entering a one-time password generated by the app. The app can store multiple accounts, including non-Microsoft accounts like Facebook, Amazon, Dropbox, Google, LinkedIn, and GitHub.
Passwordless sign-in allows users to log in to their Microsoft accounts using their phone instead of a password. After entering a username, a notification will be sent to your phone for approval using your fingerprint, face ID, or PIN.
With password autofill, the Authenticator app can save and sync passwords across different devices, including those saved in Microsoft Edge. Passwords are protected by multi-factor authentication, and users can import passwords from other password managers.
For work or school accounts, the app can also register devices and issue certificates for cert-based authentication. Microsoft Authenticator supports single sign-on for easy access to Microsoft apps and services on mobile devices.
Optional access permissions include accessibility service for autofill on more apps, location for organizations requiring location information, camera for scanning QR codes, and reading the contents of storage for diagnosing technical issues.
