RIS Cloudflare CAPTCHA is a simple yet powerful plugin that integrates Cloudflare’s CAPTCHA (Turnstile) into your WordPress site.

Additionally, you can enable CAPTCHA on all forms across your site, including the comment section, to prevent spam and other malicious activities.

This plugin is an independent, third-party integration and is not affiliated with or endorsed by Cloudflare, Inc.
<h4>Protected locations</h4>
<ul>
<li>Login form — blocks brute-force and credential-stuffing attacks</li>
<li>Registration form — prevents automated account creation</li>
<li>Comment form — stops spam comments without Akismet</li>
<li>Contact Form 7 — automatically protects every CF7 form on your site</li>
</ul>
<h4>Features</h4>
<ul>
<li>Live status checker — the settings page shows instantly whether your API keys are valid and reachable</li>
<li>Invisible mode — widget stays hidden; the form auto-submits once the challenge passes silently</li>
<li>Three themes — Auto (follows system preference), Light, Dark</li>
<li>Two appearance modes — Always visible, or show on interaction only</li>
<li>Clean uninstall — all plugin options are removed on deletion, including multisite support</li>
<li>Translation ready — all strings wrapped in i18n functions with the correct text domain</li>
<li>No bundled libraries — only Cloudflare’s own CDN script is used; nothing extra added to your site</li>
</ul>
<h4>Why Turnstile?</h4>
Unlike reCAPTCHA, Cloudflare Turnstile does not track users across sites or require Google accounts. It is designed to be GDPR-friendly and invisible to legitimate users by default.
