설명
Cybernob Turnstile for Cloudflare integrates Cloudflare Turnstile into your WordPress site — the privacy-friendly CAPTCHA that stops bots silently, without making real users solve puzzles.
This plugin is an independent, third-party integration and is not affiliated with or endorsed by Cloudflare, Inc.
Protected locations
- Login form — blocks brute-force and credential-stuffing attacks
- Registration form — prevents automated account creation
- Comment form — stops spam comments without Akismet
- Contact Form 7 — automatically protects every CF7 form on your site
Features
- Live status checker — the settings page shows instantly whether your API keys are valid and reachable
- Invisible mode — widget stays hidden; the form auto-submits once the challenge passes silently
- Three themes — Auto (follows system preference), Light, Dark
- Two appearance modes — Always visible, or show on interaction only
- Clean uninstall — all plugin options are removed on deletion, including multisite support
- Translation ready — all strings wrapped in i18n functions with the correct text domain
- No bundled libraries — only Cloudflare’s own CDN script is used; nothing extra added to your site
Why Turnstile?
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.

External Services
This plugin connects to Cloudflare’s Turnstile service to display CAPTCHA challenges and verify user responses.
- Service: Cloudflare Turnstile
- When used: When a protected form is loaded (widget script) or submitted (token verification). Only active after the administrator has entered API keys in the plugin settings.
- Data sent: On verification — the Turnstile response token and the visitor’s IP address are sent to Cloudflare’s API endpoint.
- Endpoint: https://challenges.cloudflare.com/turnstile/v0/siteverify

FAQ
-
Do I need a Cloudflare account?
-
Yes. A free Cloudflare account is required to generate Turnstile API keys. Sign up at cloudflare.com.
-
Does this work with Contact Form 7?
-
Yes. If Contact Form 7 is installed and active, this plugin automatically injects the Turnstile widget into every CF7 form and validates the token before mail is sent. No changes to your CF7 forms are needed.
-
Does this work with WooCommerce?
-
WooCommerce integration is not included in the current version. It is planned for a future release.
-
Will this slow down my site?
-
No. The Cloudflare Turnstile API script is loaded asynchronously and deferred from Cloudflare’s global CDN. It has a negligible effect on page load time.
-
Is this GDPR compliant?
-
Cloudflare Turnstile is designed to be privacy-preserving. This plugin does not set any cookies itself and only stores your API keys in the WordPress database. Please review Cloudflare’s privacy policy for their full data handling practices.
-
The status checker shows “Connection Failed”. How do I fix it?
-
Your server cannot reach
challenges.cloudflare.com. This is typically a firewall or outbound network restriction on your hosting server. Contact your hosting provider and ask them to allow outbound HTTPS connections to Cloudflare’s IP ranges. -
The status checker shows “Invalid Secret Key”. What does that mean?
-
The Secret Key you entered was rejected by Cloudflare. Double-check that you have copied the full key correctly from your Turnstile dashboard and that it belongs to the correct site widget.
-
Can I use invisible mode?
-
Yes. Enable Invisible Mode in the Widget Options section. The widget will be hidden from users and the form will auto-submit once the challenge has passed silently in the background.
