In this context, Cloudflare Turntile is a valid alternative to traditional CAPTCHA, offering a more smooth and modern user experience, without compromising the effectiveness of security measures.
In this guide we will see how to implement Cloudflare Turnstile on WordPress using the free plugin Simple Cloudflare Turntile, with particular attention to integration on native modules, comments and eCommerce platforms like WooCommerce.

To start, you need to install the plugin Simple Cloudflare Turntile directly from the official WordPress repository or by clicking here. Once activated, the new menu item will appear in the Settings section: “Cloudflare Turnstile”

General Settings and Customization
The plugin interface allows flexible customization of the Turnstile widget:
