What are CAPTCHA and 2Captcha?

Published on .

CAPTCHA and 2Captcha are two different things. CAPTCHA is a test to prove that the users are humans. While 2Captcha is a service that can solve CAPTCHA automatically.

What is CAPTCHA?

CAPTCHA stands for "Completely Automated Public Turing test to tell Computers and Humans Apart". Many websites use it to prevent bot spamming. CAPTCHAs provide challenges that can be done by humans.

CAPTCHA tests often involve asking the user to type in text that is displayed in an obscured image or audio file.

Two common CAPTCHAs that I commonly find are reCAPTCHA and hCaptcha.

Why does CAPTCHA exist?

According to Statista, bots accounted for 42.3% of worldwide Web traffic in 2021.

Bots can be used to spam, scrape information, and many other things. They can create issues for social media platforms. For example, they can do promotion by commenting on each person that posts something. They can be annoying for humans.

CAPTCHA solves this issue by making sure that humans are accessing the platform. It provides a challenge that only real humans can solve—although not all humans can solve it.
