reCAPTCHA is a free Google service that protects your site from spam and abuse. It uses advanced risk analysis techniques to tell humans and bots apart.

To start using reCAPTCHA, you will need to sign up for an API key pair for your site. The key pair consists of a site key and secret key. The site key is used to invoke reCAPTCHA service on your site or mobile application. The secret key authorizes communication between your application backend and the reCAPTCHA server to verify the user's response. The secret key needs to be kept safe for security purposes.
Once you have an API key pair for your site, you will plug in these values into MAIN SETTINGS > Google Recaptcha and select the form to apply it to.
