How to generate site & API keys
1- Create an account on the Friendly Captcha website (it's free), then log in to your account.
2- Generate a sitekey under Applications page. Click "Create New Application" and enter the necessary details. Once you have completed this, take note of the sitekey value under the application name. A sitekey always starts with the characters FC.
3- Create an API Key on the API Keys page located in the dashboard.
