What is a Turnstile CAPTCHA

A Turnstile CAPTCHA is a modern, user-friendly CAPTCHA system developed by Cloudflare designed to distinguish between human users and bots. Unlike traditional CAPTCHAs that often require users to solve puzzles or identify images, Turnstile can operate invisibly, analyzing user behavior and other signals to authenticate users without interrupting their experience. This approach minimizes friction for legitimate users, making it easier for everyone to access and interact with websites while providing robust protection against spam and automated attacks. Turnstile is easy to integrate, accessible, and free, offering a seamless balance between security and user experience.
