Captcha is a test that allows users to demonstrate that they are actual people, not robots. “Completely Automated Public Turing test to tell Computers and Humans Apart” is what the acronym “CAPTCHA” stands for.

This challenge-response test can be used to determine whether the response was produced by a human being as opposed to a computer. There are currently more than ten different types of captcha on the market, and you can integrate them into your website to prevent spam.

Text captcha, image captcha, audio captcha, puzzle captcha, math captcha, word problem captcha, and other common captcha kinds are only a few. Why does this matter, though? We then reveal that to you.
