How to sign up for an API key pair for your site

To use reCAPTCHA, you need to sign up for an API key pair for your site. The key pair consists of a site key and a secret. The site key is used to display the widget on your site. The secret authorizes communication between your application backend and the reCAPTCHA server to verify the user's response. The secret needs to be kept safe for security purposes.
