A CAPTCHA is a website challenge used to distinguish human visitors from automated programs.

CAPTCHA stands for “Completely Automated Public Turing test to tell Computers and Humans Apart.” Websites use these challenges, which may involve entering text or selecting images, to distinguish people from automated programs and limit bot activity.

Unlike a password, which checks a user’s identity, a CAPTCHA attempts to determine whether an interaction comes from a person.
