The Login Toboggan module improves the Drupal login system by offering the following features:
- Allow users to login using either their username OR their email address.
- Allow users to define their own password.
- Allow users to login immediately.
- Provide a login form on Access Denied pages for non-logged-in (anonymous) users.
- The module provides two login block options: One uses JavaScript to display the form within the block immediately upon clicking "log in". The other brings the user to a separate page, but returns the user to their original page upon login.
- Customize the registration form with two email fields to ensure accuracy.
These features may be turned on or off in the Login Toboggan settings.
Feel funny about people logging in at "http://yoursite.com/toboggan/login"? (Yes, we know it\'s a silly name.) You can use the path.module\'s "url aliases" to redefine Login Toboggan\'s paths as something else (perhaps: "usr/login" or just "login").
Because this module completely reorients the Drupal login process you will probably want to edit the welcome email on the user settings page. For instance if you have enabled "Set passwords during registration" you probably should not send the user\'s password out in the welcome email. Also when either "Set passwords during registration" or "Immediate login" are enabled, the %login_url becomes a verification url that the user MUST visit in order to enable authenticated status. The following is an example welcome email:
', array('%url' => url('admin/settings/logintoboggan')));
$example = t('
%username,
Thank you for registering at %site.
IMPORTANT:
For full site access, you will need to click on this link or copy and paste it in your browser:
%login_url
This will verify your account and log you into the site. In the future you will be able to log in using the username and password that you created during registration.
Your new %site membership also enables to you to login to other Drupal powered websites (e.g. http://www.drupal.org/) without registering. Just use the following Drupal ID along with the password you\'ve chosen:
Drupal ID: %username@%uri_brief
-- %site team');
