A CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a type of challenge–response test used in computing to determine whether or not the user is human. CAPTCHAs are designed to prevent automated abuse of online services, such as logins and signups, by requiring the user to answer a question or solve a randomised visual puzzle. They are used to protect websites from automated malicious activities like spam and identity theft, as well as to add an extra layer of security when logging into accounts.
