When registering on a site a user will normally be asked for password verification which is required in Drupal by default.
Sometimes clients elect to have the given mechanism disabled. Web developers can do that by adding the following code to this module:
/** * Implementation of hook_form_alter() */ function mymodule_form_alter(&$form, $form_state, $form_id) { switch ($form_id) { case 'user_register': drupal_add_js("Drupal.behaviors.password = function(context) { return; }", 'inline' ); break; } }
