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.
Flexible authentication controls are just one factor to consider when you're choosing a 2FA solution. Read our guide to learn how to spot a good solution and evaluate vendors, so that you end up with a product truly meets your company's needs.
