3. Log in to your Drupal site as the administrator.

4. On the top menu bar, click Modules, and then click Install new module.

   Note

   By default, the Drupal CAPTCHA module uses math problems for CAPTCHA tests. If you want to use image-based CAPTCHA tests, enable the
   Image CAPTCHA module also.

8. Click Save configuration.

9. Scroll down to SPAM CONTROL again, and click Configure for the CAPTCHA module. The CAPTCHA module configuration page appears.

10. You can now define which areas of your site are protected by CAPTCHAs. For example, to protect registration forms, locate user_register_form in the FORM_ID column, select the challenge type, and then click Save configuration. To test this, go to your Drupal site and click a register link. Drupal displays a CAPTCHA in the registration form.
