Microsoft Authenticator

Microsoft Authenticator is a comprehensive security app that provides easy and secure sign-in solutions for all your online accounts. The app offers three main features: multi-factor authentication (MFA), passwordless sign-in, and password autofill capabilities. With MFA, users can add an extra layer of security by approving notifications or entering time-based one-time passwords (TOTP) for various accounts, including non-Microsoft services like Facebook, Google, and GitHub. The passwordless feature allows users to log into Microsoft accounts using their phone instead of passwords, utilizing biometric authentication or PIN for added security. The autofill function can sync and manage passwords across devices, protected by multi-factor authentication. For work or school accounts, the app supports device registration, cert-based authentication, and single sign-on capabilities, making it easier to access Microsoft services securely. Additional features include optional permissions for autofill support, location services, QR code scanning, and technical problem reporting.
