Support Every User

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

Duo Push is our most commonly-used second-factor 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.

U2F and Biometrics

Duo allows users to physically authenticate by tapping a U2F USB device or using a built-in biometric authenticator, such as TouchID, via WebAuthn.

Tokens and Passcodes

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.
