reCAPTCHA is a free Google service that allows web hosts to distinguish between human and automated access to their websites, thereby protecting them from spam and abuse.
Only works with ReCaptcha v3.
- Site Key - the site key is used to activate the reCAPTCHA service on your website.
- Private Key - the secret key enables communication between your application's backend and the reCAPTCHA server in order to validate the user's response. For security reasons, the secret key must be kept secure.
