About

Enable MFA to add a second layer of security during login by approving a notification or entering a one-time password (OTP) with a 30-second timer. Use passwordless authentication with your phone, fingerprint, face ID, or PIN instead of a password to access Microsoft products like Outlook, OneDrive, and Office. The app supports multiple accounts including non-Microsoft services like Facebook, Amazon, Dropbox, Google, LinkedIn, and GitHub. Autofill passwords synced from Microsoft Edge or imported from Google Chrome and other password managers, protected by multi-factor authentication. For work or school accounts, the app supports certificate-based authentication to verify trusted devices.
