What is a Captcha?

A Captcha is a security tool used to distinguish between humans and automated bots. Captchas are widely used in online forms to prevent automated submissions by malicious software.

Why are Captchas important?

Captchas help protect websites against automated attacks, such as:

• Sending spam
• Creating fake accounts

How do Captchas work?
