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 contains the base UI related to all reCAPTCHA features.
