The Captcha facility is inbuilt in the Directory theme that the users can configure to protect their forms from malicious registrations and activities. There are many machines that run codes that will access website and register on it and perform malicious actions that may cause serious harm to your site.

This harm can sometimes be so serious that the entire site can be made unavailable by overloading the server with requests. Therefore, CAPTCHA is used to tell whether its the human or the machine performing the action on the website.

CAPTCHA stands for Completely Automated Public Turing Test to Tell Computers and Human Apart. This facility comes inbuilt in the Tevolution plugin. To activate it navigate to Dashboard >> Tevolution >> Settings >> General Settings >> Captcha and fill the following form to activate it.
