Duo uses push notifications, time-based, one-time passwords, physical tokens and biometrics to verify the identity of users at login. Similarly, Microsoft Authenticator uses push notifications, one-time passcodes, and biometrics for authentication and can integrate with Microsoft 365 and Azure Active Directory. While both 2FA options share some similarities, there are still key differences that can sway your decision to choose one over the other.
