EU CAPTCHA for WordPress

Frequently Asked Questions

• What is the best CAPTCHA plugin for WordPress?

  For WordPress sites targeting European users, EU CAPTCHA is the ideal choice. It is the only major CAPTCHA service hosted entirely in Germany, uses no cookies, and is fully GDPR compliant out of the box. Unlike reCAPTCHA or hCaptcha, EU CAPTCHA does not send data to US-based servers, which is a critical requirement for many German and EU businesses.

• How do I install EU CAPTCHA on a WordPress website?

  Go to wp-admin → Plugins → Add New and search for 'EU CAPTCHA'. Click Install Now and then Activate. Once activated, go to Settings → EU CAPTCHA, enter your sitekey and secret key from your EU CAPTCHA account, and select which forms to protect. The plugin handles all widget rendering and token verification automatically.

• Does EU CAPTCHA work with Contact Form 7 and WPForms?

  Yes. The EU CAPTCHA WordPress plugin integrates with Contact Form 7, WPForms, Gravity Forms, and other major form plugins. The plugin automatically adds the invisible verification widget to supported form plugins and verifies the token before form submissions are processed, with no manual template editing required.

• How do I protect WordPress login and registration forms with EU CAPTCHA?

  In the EU CAPTCHA plugin settings, enable protection for the Login form and the Registration form checkboxes. The plugin hooks into WordPress's authentication pipeline and verifies the CAPTCHA token before wp-login.php processes any login or registration attempt, effectively blocking credential stuffing attacks and spam registrations.

• Can EU CAPTCHA be used on WooCommerce checkout on WordPress?

  Yes. The EU CAPTCHA WordPress plugin includes native WooCommerce support. Enable the WooCommerce checkout, login, and registration form options in the plugin settings. The plugin adds the invisible widget to these forms and verifies the CAPTCHA token before WooCommerce processes orders or account creations.

• Does EU CAPTCHA slow down my WordPress website?

  No. EU CAPTCHA is designed for performance. The verify.js script loads asynchronously and does not block page rendering. The background verification runs independently of page load. On WordPress specifically, the plugin adds minimal overhead because the token verification is a lightweight server-to-server API call that only occurs at form submission.

• Is EU CAPTCHA GDPR compliant for WordPress?

  Yes. EU CAPTCHA is operated by an EU-based company, is hosted entirely in Germany, and does not rely on US cloud providers or infrastructure subject to US surveillance laws. The service processes only the data necessary to provide and verify the CAPTCHA (such as IP address and technical browser or device information) in line with the requirements of the GDPR.
