If your computer does not have Bluetooth, you will need to use a Bluetooth Adapator, sometimes also refereed to as Bluetooth Dongle. If its for your personal computer, you can purchase a suitable device from most major retail stores. If for your work computer here at UAPTC please contact IT Services. If your phone does not have Bluetooth or you do not want to enable it, you will have to use a YubiKey instead, which can be obtained from the IT Helpdesk.
