<p>Frontend Gatekeeper hides the public frontend of your WordPress site unless visitors arrive with a configured URL parameter and value. It is useful for staging sites, soft launches, client previews, and pre-release content where you want to share a single shareable link instead of issuing individual user accounts.</p>
<p>Logged-in users always see the site normally, so editors and administrators are never blocked.</p>
<h4>Features</h4>
<ul>
<li>Hide the entire public frontend with a single toggle.</li>
<li>Configurable parameter name and secret value, set per site.</li>
<li>Custom blocked message shown to unauthorized visitors (served with a 404 status).</li>
<li>Same-site link propagation: WordPress-generated links, menus, and block content automatically carry the access parameter forward, so visitors stay authorized while browsing.</li>
<li>Footer-script fallback that adds the parameter to links and forms rendered outside normal WordPress filters.</li>
<li>Gutenberg and block-theme aware through the <code>render_block</code> filter and <code>WP_HTML_Tag_Processor</code> when available.</li>
<li>Multisite-aware URL scoping for subdomain and subdirectory networks: access on <code>/site-a/</code> will not leak the token to <code>/site-b/</code>.</li>
<li>Logged-in users, wp-admin, REST API, AJAX, cron, and <code>wp-login.php</code> are always allowed through.</li>
</ul>
<h4>Typical use cases</h4>
<ul>
<li>Sharing a staging or pre-launch site with clients and stakeholders.</li>
<li>Gating a soft launch behind a single link instead of provisioning accounts.</li>
<li>Hiding draft or campaign content until you are ready to publish.</li>
</ul>


Frontend Gatekeeper

Hide the public WordPress frontend behind a secret URL parameter. Anyone with the link gets in; everyone else sees a 404.

<h4>Quick Overview</h4>
<p>Subway is a small plugin for WordPress that allows you <strong>hide the content</strong> of your website to <strong>non-logged in</strong> visitors and only displays them to logged in users.</p>
<h4>Description</h4>
<p>This plugin redirects the users to the provided login page with a login form that allows them to type their username/email and password combination.</p>
<p>The plugin has settings inside the Administration Panel (‘Settings’ > ‘Subway’) that allows you to configure where you want the user to be taken after he/she has successfully logged in, this can be a page, a custom URL, or just the default behaviour. You can also make individual posts/page public or ‘members only’</p>

<p>Subway is only built for WordPress website owners to redirect non-logged in users to a custom login form. This plugin is not a replacement for Membership websites where a complex set of configurations are allowed. There are no payments model, subscriptions.</p>
<p>Subway is good for Private Intranet Websites where authentication is required.</p>
