reCAPTCHA keys, also known as site keys, let you protect your endpoints by verifying user interactions on your web pages and mobile applications.

reCAPTCHA Enterprise provides the following site keys:

  • Score-based (no challenge) site keys: Score-based site keys let you verify whether an interaction is legitimate without any user interaction. You can use score-based site keys on web pages and mobile applications.

  • Checkbox (checkbox challenge) site keys: Checkbox site keys use a checkbox challenge that requires user interaction to verify that the user is not a robot. Also, you can use checkbox site keys to protect specific actions with CAPTCHA challenges. You can use checkbox site keys only on web pages.

  • reCAPTCHA WAF site keys: reCAPTCHA WAF site keys let you protect your site from spam and abuse at the web application firewall (WAF) layer. These site keys let you implement features of reCAPTCHA Enterprise with WAF for a WAF service provider, such as Google Cloud Armor. For more information, see reCAPTCHA Enterprise for WAF and Google Cloud Armor integration overview.

These site keys return a score for each request, which is based on the interactions with your site or application. By interpreting these scores, you can take appropriate actions for your site or application.

The following table lists the supported site keys and their integration types for each platform:
