how to customized user login page My question is when i  browse  my admin site www.example.com/user a simple login page will appear.


Here in this login form there is no option for forget password .so I need option to request new password and new password can be send through email.
You can make a template to alter your user login form.

In template.php:

function YOURTHEMENAME_theme(){
    return array(
        'user_login' =&gt; array(
            'arguments' =&gt; array('form' =&gt; NULL),
            'render element' =&gt; 'form',
            'template' =&gt; 'templates/user-login-form',
        ),
  );
}


Then create user-login-form.tpl.php in your template folder and print the login form using

print drupal_render_children($form);
