Learn How to Add CAPTCHA to a Joomla 4 Site

In this guide, we will show you how to add CAPTCHA to a Joomla 4 site. When you first installed Joomla 4, you may have noticed some spam submitted on your registration form. This is typically generated by robots or bots that crawl the web looking for websites to post spam on. Since it is not valid visitor traffic, it does not add any value to your website.

These bots can be deterred by using CAPTCHA on your forms. CAPTCHA is a basic test that can help verify if your form is being filled out by a real human.
