Push notification approval offers one-tap authentication for Microsoft accounts eliminating manual code entry. Passwordless sign-in for Microsoft accounts removes passwords entirely using biometric authentication. The app works offline generating codes locally without internet connectivity. Biometric app lock protects authenticator codes with fingerprint or face recognition. Cloud backup syncs accounts across devices preventing loss when switching phones. Support for third-party services includes Google, Facebook, Amazon, and countless others through standard TOTP protocol. Microsoft accounts benefit from additional features like app passwords and security info management.
