Saturday, March 31st, 2018, Google is discontinuing its service of reCAPTCHA Version 1, replacing it with the improved reCAPTCHA Version 2.
reCAPTCHA is a tool used to protect against spam accounts being created on a site when using email-based self-registration. Version 1 requires users to type out a set of numbers and letters displayed on the screen to prove they aren’t a robot before allowing them to register. As of March 31st, 2018, Version 1 will no longer work. That means that no new self-registrations will be possible on sites configured to use email-based self-registration with reCAPTCHA enabled until action is taken.
In order to take advantage of reCAPTCHA v2, sites must be running Moodle™ 3.1 or higher. If you are not able to upgrade your site to one of the supported versions at this time, self-registration can still be used on your site by disabling the reCAPTCHA element with the following steps:
- To disable reCAPTCHA v1 on your site, navigate to Site administration ► Plugins ► Authentication ► Email-based Self-registration.
- Toggle the Enable reCAPTCHA element setting to “No”.
- Click Save changes at the bottom of the screen to commit the new setting to the server.
Please note: If you plan to continue email-based self-registration on your site, doing so without a service like reCAPTCHA does open up a security risk. Remote-Learner recommends upgrading your site in the near future to take advantage of the improved reCAPTCHA v2. For more information about site upgrades, please contact your Account Manager.
