This plugin enhances your WordPress login security by allowing you to change the default login URL (wp-login.php) to a custom slug of your choice. It also blocks direct access to wp-login.php and wp-admin for non-logged-in users.
By default, the custom login slug is set to mysecretlogin when the plugin is activated.
If you change or update the custom login slug, you must re-save your permalinks (go to Settings > Permalinks and click “Save Changes”) to ensure the new login URL works correctly.

Custom Login URL (CLU) is a lightweight plugin that allows to customize default WP login, registration and password 
reminder URLs without modifying any files, simple and swift.
Why would anyone would want to use this plugin? Well, after developing some sites it turned 
out that site owners do not want to reveal to customers that they are using WordPress, hence the plugin that will mask 
original URLs.
What the plugin can do:
<ul>
<li>change /wp-login.php to for example /user/login/</li>
<li>change /wp-login.php?action=register to for example /user/register/</li>
<li>change /wp-login.php?action=lostpassword to for example /user/remind/</li>
<li>change /wp-login.php?action=logout to for example /user/logout/</li>
<li>you can define your own custom paths for each URL above</li>
<li>set successfull login and logout redirect URLs</li>
</ul>
In order to make the plugin work you need to have Permalinks enabled in WP Settings.
