This documentation is not using the current rendering mechanism and is probably outdated. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.
Setting the Yubico API Key¶
After installing the extension from the extension repository, you need to configure the extension settings. The authentication process only works, if you provide a Yubico API Key, which can by obtained at https://upgrade.yubico.com/getapikey/
The Yubico API Key is necessary to use the free YubiCloud OTP validation service.
After you have obtained your Yubico API Key, enter the Client ID and the Client Key in the extension settings.
