Before you can use the Yubikey Authentication system, you need a Yubikey Hardware Device.
Once you have one of these devices, you can generate yourself a Yubikey application ID. You will need this so that the plugin may communicate with the Yubikey authentication servers.
To generate your Yubikey application ID and key, please go here:
Simply enter your registered Yubikey email address and then enter a Yubikey One Time Password (OTP). The site will then return you two pieces of information.
- Client ID - which you put into the App ID field of the plugin.
- API Key - which you put into the API Key field of plugin.
Once these are entered the Yubikey functionality is ready to run.
