Approx. read time : 2 min

CAPTCHA stands for “Completely Automated Public Turning Test to indicate Computers and Humans Apart”.
It is an important tool that is used in computing to determine whether the user is human or not. It is used to prevent your contact forms from being used by automated spambots visiting your site. CAPTCHA protects your information or work by displaying distorted images with some letters or digits on your screen. So the humans need to type the letters or solve arithmetic equations, etc. before they can submit the form. The reason behind CAPTCHA use is that automated bots can’t read and type the displayed CAPTCHA problems and thus, are unable to use your forms to generate spam.

Your WordPress site also needs CAPTCHA protection, in order to protect it from spamming by spambots and other harmful actors. This article will guide you on how to add CAPTCHA protection to a WordPress site using the Google Captcha (reCAPTCHA) plugin.
