Email-based self-registration enables a user to create their own account via a \'Create new account\' button on the login page. The user then receives an email containing a secure link to a page where they can confirm their account. Future logins just check the username and password against the stored values in the Moodle database.
Note: In addition to enabling the plugin, email-based self-registration must also be selected from the self registration drop-down menu on the \'Manage authentication\' page.
