Which YubiKey should I Choose?
When deciding which YubiKey to purchase from the recommended list, consider the USB Type. If you primarily use computers that have a USB-A connection, choose from the available USB-A models. If you primarily use computers that have a USB-C connection, choose from the available USB-C models. Some YubiKey models, such as the 5 Series, support a wide array of authentication methods that can be used with other services. However, for DUO, any YubiKey listed in the compatible YubiKeys list will work.
