Duo lets your users access their applications securely, no matter the circumstance. Employee left their phone at home? Need to authenticate without an internet connection? Want a passcode-free login experience? Check, check, check — Duo’s got you covered.
Duo Push is our most commonly used second-factor (2fa) authentication method, thanks to its simplicity and reliability. Users just download the Duo Mobile app and are automatically prompted to confirm each login attempt — all it takes is a single tap. For a more secure option, users can complete Verified Duo Push by entering a unique code from the login device on the Duo Mobile app.

Duo allows users to physically authenticate by tapping a security key or using a built-in biometric authenticator, such as TouchID, via WebAuthn.
Duo also accommodates more traditional second-factor authentication controls. Users can confirm their identity using a secure passcode generated by a physical token, a mobile device, or a network administrator.
