Cloudflare Turnstile is a smart CAPTCHA alternative designed to verify legitimate human users and block bots, without the intrusive challenges often associated with traditional CAPTCHAs. This script initializes and manages the Turnstile widget on a webpage. It leverages various signals from the user's browser during a short challenge to determine if the user is human, presenting minimal or no interaction required for the user. It helps protect websites from spam, credential stuffing, and other automated attacks, ensuring a smooth user experience while maintaining security. The script dynamically injects and manages the Turnstile iframe and communicates with Cloudflare's backend services to perform the verification process, enhancing website security and integrity.
