Prior to this set up, you will need to already have a supported YubiKey USB device.
In the Alternative Authentication popup window, select 'Authenticate with YubiKey,' and then click Next.
Insert the YubiKey into your computer USB port, make sure the Alternative Authentication window is selected, and then tap the YubiKey.
Now, a one-time passcode (OTP) will be automatically generated and inserted into the YubiKey Setup window and the Verify button will be selected automatically. You'll then see a green checkmark icon indicating successful pairing and authentication.
Next time you log in using KochID, you'll be prompted to enter a YubiKey OTP. Simply press your YubiKey button to generate the necessary OTP and click Sign On to authenticate yourself.
