wSecure hides admin URL so that default URL will no longer bring up the admin page. Only people who enter the secret key will be able to access admin
The wSecure plugin hides admin URL so that "www.yoursite.com/wp-admin" will no longer bring up the admin page. Instead, wSecure allows you to set your own admin URL using a secret key (for example: http://www.yoursite.com/wp-admin/?secret). Only people who enter the secret key will be able to access your admin area.
Features: The Basic Version will hide your administrator URL from public access. This is all most people need.
The Advanced version has additional features that you can have.
