Google reCAPTCHA ensures that a human being, rather than a computer (or “bot”), is interacting with your website. Unlike the standard Magento CAPTCHA, Google reCAPTCHA provides enhanced security with a selection of different display options and methods. Additional website traffic information is available in the dashboard of your Google reCAPTCHA account.
This module provides the UI related to customer-facing reCAPTCHA views.
