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:

change /wp-login.php to for example /user/login/
change /wp-login.php?action=register to for example /user/register/
change /wp-login.php?action=lostpassword to for example /user/remind/
change /wp-login.php?action=logout to for example /user/logout/
you can define your own custom paths for each URL above
set successfull login and logout redirect URLs

In order to make the plugin work you need to have Permalinks enabled in WP Settings.
