Past this code into a php file into the root of your wordpress site. If you host for some reason has disabled access to wp-login.php because of a current brute force hack, this will still allow you access to your WordPress Dashboard. The logout link of your site will not work but you can add ?logout to any url and be logged out.
$wp_login = file_get_contents('./wp-login.php');
$newPage = str_replace('wp-login.php',ltrim($_SERVER['PHP_SELF'],'/'),$wp_login);
eval( rtrim( ltrim( $newPage, '<?php'),'?>') );
