Webform Captcha is an essential security feature that helps protect your Drupal 8 website's forms from spam and automated submissions. By adding a CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) to your webforms, you ensure that only human users can submit the form, preventing bots from inundating your website with unwanted content.
Webforms are an integral part of engaging with your website visitors, but they can be vulnerable to spam and bot-generated submissions. Implementing a CAPTCHA to your Drupal 8 webforms is an effective way to safeguard your forms and maintain data integrity. In this guide, we'll walk you through the process of installing, configuring, and customizing the Drupal 8 Webform Captcha module to enhance your website's security.
