Once you have your App ID and API Key, please follow these steps:

  1. Go to Shield plugin => Login Guard => 2FA-Yubikey => enable Yubikey Authentication => enter your App ID and API Key (see the screenshot below)
  2. Go to Users => your Profile page
  3. At the bottom of the page you'll see an area where you can input your Yubikey. Simply supply a Yubikey One-Time-Password in the text field and save. (See the screenshot below)
