Key Questions Answered
CAPTCHA stands for Completely Automated Public Turing test to tell Computers and Humans Apart. It is a security mechanism designed to help websites determine whether a visitor is a real person or an automated software program known as a bot.
Websites use CAPTCHA to protect against automated abuse, such as malicious bots creating fake accounts, posting spam, flooding comment sections, or executing large-scale login attempts using stolen passwords.
Repeated verification checks can be caused by unusual traffic from an internet connection, rapid sequential requests, strict browser settings, or using a VPN or shared network connection that the website's security system flags as suspicious.
