Joomla Service Provider

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: 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 the feature that most people need.
Basic Configuration
<ul>
<li>Set “Enable” to “yes” in order for wSecure to work.</li>
<li>The “Pass Key” field allows admin to select the mode in which admin can enter the “Secret Key” to access the WordPress admin login page. Possible options are directly through “url” or a separate “form” asking to enter the secure key. </li>
<li>In the “Key” field enter the key that will be part of your new administrator URL. For example, 
 if you enter “wSecure” into the key field, then the administrator URL will be http://www.yourwebsite/wp-admin/?wSecure </li>
<li>If you do not enter a key, but enable the wSecure plugin, then the default URL to access the administrator area is /?wSecure 
 (http://www.yourwebsite/wp-admin/?wSecure)</li>
<li>Set the “Redirect Options” field. By default, if someone tries to access you /wp-admin URL without the correct key, they will be redirected to the home page of your WordPress site. You can also set up a “Custom Path” is you would like the user to be redirected somewhere else, such as a 404 error page.</li>
<li>Set “Captcha Status” to “yes” to enable Google reCaptcha on WordPress Admin Form.</li>
<li>In Re-Captcha Secret Key textbox enter secret key value.</li>
<li>In Re-Captcha Site Key textbox enter site key value.</li>
