Duo allows you to register a U2F Token as a second-factor device. This token is a small device designed to carry on a keychain that plugs into a USB port on your computer. We use a U2F token called a YubiKey, but all U2F tokens require the use of the Chome Chrome web browser and access to a USB port to function. If you have a newer Macbook, you may be required to use a USB-C to USB adaptor to use this option. While on the Duo screen, you will plug in your YubiKey to an available USB port on your computer. The key symbol on the token will begin to blink, and once it does you will touch the key symbol. Once Duo has recognized that the YubiKey has been touched you will be authenticated and given access to your account. |
