What is CAPTCHA?

A captcha is a security measure used in online forms or websites to distinguish between human users and automated bots. It typically involves presenting users with a challenge, such as typing distorted characters or selecting images, to verify their identity. Captchas help prevent spam, fraud, and unauthorized access to online services by ensuring that only genuine users can proceed.
