Configuring Image CAPTCHA
To adjust the default Image CAPTCHA settings navigate to Administer > Configuration > People > CAPTCHA and click the Image CAPTCHA tab in the top right
Navigate to Administer > Configuration > People > CAPTCHA and click the CAPTCHA tab in the top right.
This page allows you to set what type of CAPTCHA site users will be presented with, on which pages and how often.
Select the appropriate Challenge Type: Math, Image or reCAPTCHA for each instance.
Depending on the site settings, Permissions or Roles you can deploy CAPTCHA in various ways. We recommend at least configuring reCAPTCHA as the Challenge Type for user_register_form and contact_site_form as those forms are generally exposed to everyone. All the others may (depending on other settings) require a User to be logged in, and thus have already proved their identity.
A Challenge description is added by default to the CAPTCHA. Toggle the option here and change the phrasing.
When done click Save configuration.
To test, try registering as new User (with a different email address from any previously used on your site) to see if you need to make any further adjustments.
