How do I use Duo Security with a Yubikey?

If you do not own a cell phone, a tablet or any sort of mobile device that will work for authenticating a Duo log-in, you will need to use a Yubikey. These devices work by generating a passcode during your log-in attempt.

Note: A Yubikey requires a USB port.  It will only work on a device that has a USB port.

Note: Your Yubikey will allow you to login to CAS services such as Bmail and myBucknell.  You cannot login to the VPN using a Yubikey.

    3. Use the drop down menu next to Device: to select Token.
    4. When Duo Security prompts you on the next screen to authenticate the log-in, select "Enter a Passcode".
