EU CAPTCHA for Drupal

Frequently Asked Questions

• How do I add EU CAPTCHA to a Drupal website?

  Install the EU CAPTCHA Drupal module via drush using drush en eu_captcha, or upload and enable it through the Drupal admin interface under Extend → Install new module. After activation, navigate to Configuration → EU CAPTCHA, enter your sitekey and secret key, and enable protection on the forms you want to protect.

• Is there an official EU CAPTCHA module for Drupal?

  Yes. EU CAPTCHA provides an official Drupal module that integrates with Drupal's form system. The module handles widget rendering and server-side token verification automatically. It is available for download from the EU CAPTCHA documentation and supports Drupal 9, 10, and later versions.

• Does EU CAPTCHA work with Drupal's Webform module?

  Yes. The EU CAPTCHA Drupal module integrates with Webform, which is the most widely used form builder for Drupal. Once enabled, you can select which Webform submissions require CAPTCHA verification from the module configuration page, protecting custom contact forms, registration forms, and application forms built with Webform.

• How do I protect Drupal user registration with EU CAPTCHA?

  In the EU CAPTCHA module settings, enable protection for the user_register_form. The module hooks into Drupal's form_alter system to add the invisible widget to the registration form and verifies the token via Drupal's validation pipeline before user accounts are created, effectively preventing automated spam registrations.

• How do I install the EU CAPTCHA module using Drush?

  Run drush en eu_captcha to enable the module. If it is not yet downloaded, use composer require drupal/eu_captcha first, then drush en eu_captcha and drush cr to rebuild the cache. After installation, configure your sitekey and secret key in the module settings and enable the forms you want to protect.

• Is EU CAPTCHA compatible with Drupal 9, 10, and 11?

  Yes. The EU CAPTCHA Drupal module is maintained for current Drupal versions. Check the module's documentation for the supported version matrix. The module uses standard Drupal APIs (form_alter, hook_form_validate) that are stable across major Drupal versions, making upgrades straightforward.

• Is EU CAPTCHA GDPR compliant for Drupal websites?

  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.
