Create a referrer to the WordPress wp-admin. You can create any path and the plugin will only allow the login form to show once it detects the correct reference URL. No core files hacked.
If yoursite.com/wp-admin or yoursite.com/wp-login.php are used, the user is redirected to the home page. When the correct URL is detected eg: yoursite.com/adminaccess, the plugin then allows the user to access the login form, which is still wp-login.php
This is primarily for websites that do not allow registered user login because it will also require that those users know the referring URL, and that defeats the purpose.

CMSE Secret Admin

Josh Eaton

A small plugin that lets you “hide” the front-end of a site, all front-end requests of logged-in users are redirected to the WP Dashboard (filterable).
Useful mainly for developers, if you’re developing a site and want to give users access to see the dashboard while you’re working on the front-end. Also can be used if you have a site with no front-end and always want users to stay on the dashboard.
Filters included:
<ul>
<li><code>rfe_redirect_caps</code>: Control capabilities required to bypass redirect, lets Administrators access front-end by default (default: <code>manage_options</code>) </li>
<li><code>rfe_redirect_url</code>: Change the redirect URL (default: <code>admin_url()</code>)</li>
</ul>
