What is CAPTCHA?

Anyone who has ever used the internet has probably encountered captcha challenges. You probably already know what a captcha is, but to cover all the bases, let’s take a quick look at what you need to know before installing a captcha tool on your site.

Captcha is a test for humans to prove that they are real people and not bots. The word ‘CAPTCHA’ is an acronym for “Completely Automated Public Turing test to tell Computers and Humans Apart”.

This is a challenge-response test that can help determine whether the response was generated by a human and not a computer.

There are now more than 10 types of captcha available in the market, and you can add them to your website to block spammers.

Some of the most popular captcha types include text captcha, estonia phone number library image captcha, audio captcha, puzzle captcha, math captcha, word problem captcha, etc.
