A security key is an external device that when tapped or when the button is pressed sends a signed response back to Duo to validate your login. Duo uses the WebAuthn authentication standard to interact with your security keys. You may also see WebAuthn referred to as "FIDO2".

To use a security key with Duo, make sure you have the following:

• A supported security key. WebAuthn/FIDO2 security keys from Yubico or Feitian are good options. U2F-only security keys (like the Yubikey NEO-n) can't be used with the Universal Prompt.
• A supported browser: Chrome, Safari, Firefox, or Edge. Refer to the Duo browser support table for minimum browser versions with security key support in Duo.

1. On your computer, go to the Two-factor authentication set-up and management page. Enter your NetID username and password to login. 
2. Click the Other options link on the authentication page to view your list of available authentication methods.
   
        
   
   
3. Select the Manage devices choice at the end of the list to enter the device management portal.
   
        
   
   
4. Choose an authentication method and complete two-factor authentication to begin adding your new device.
