Talisa @ Page Authority

<p>Allowed Email Domains gives administrators a simple way to restrict WordPress user accounts to approved email domains.</p>
<p>The plugin is designed for sites where only users from specific organizations, companies, clients, or teams should be added as WordPress users.</p>
<p>Features include:</p>
<ul>
<li>Admin-managed allowed domain list</li>
<li>Standard WordPress registration enforcement</li>
<li>REST API user creation/update enforcement</li>
<li>WooCommerce registration enforcement</li>
<li>Existing User Audit tools</li>
<li>Optional login enforcement</li>
<li>Per-user unauthorized account removal with content reassignment</li>
<li>Multisite-aware protections</li>
<li>Lightweight architecture with no custom database tables</li>
</ul>
<h3>Security Notes</h3>
<p>The plugin includes:</p>
<ul>
<li>Capability checks</li>
<li>Nonce verification (verified before any state-changing logic runs)</li>
<li>Sanitization and escaping</li>
<li>Live revalidation before destructive actions</li>
<li>Current-admin protection</li>
<li>Multisite Super Admin protection</li>
<li>Explicit content reassignment or delete confirmation before user removal</li>
</ul>
<p>Recommended operational practices:</p>
<ul>
<li>Review the Existing User Audit before enabling login blocking</li>
<li>Test custom registration and SSO flows before production rollout</li>
<li>Maintain regular database backups before deleting users</li>
<li>Restrict plugin management access to trusted administrators only</li>
</ul>
<h3>Uninstall</h3>
<p>Deleting the plugin removes its current options:</p>
<ul>
<li><code>pageauth_allowed_domains</code></li>
<li><code>pageauth_audit_log</code></li>
<li><code>pageauth_block_unauthorized_logins</code></li>
</ul>
<p>It also cleans up internal flags, transients, user meta, and any leftover keys from prior plugin versions that used the <code>paad_</code> or <code>aed_</code> prefixes. On multisite, the matching network options are removed as well.</p>


Page Authority – Allowed Domains

Restrict WordPress user accounts to administrator-approved email domains.

<ul>
<li>Point multiple domains/sub-domains at a single WordPress installation and maintain link integrity (i.e. if you’re on http://foo.com, links will be http://foo.com/bar, and if you’re http://baz.com links will be http://baz.com/bar)</li>
<li>Overwrite site title, description, or theme per domain</li>
<li>Customize content per domain using the [MultiDomain_if] and [MultiDomain_else] shortcodes</li>
</ul>
<p>If you need more customization between domains, WordPress MU is a better option.</p>
<h3>Configuration Examples</h3>
<p>Note that you usually won’t need to configure your primary domain — MultiDomain will automatically fall back to your WordPress defaults if not configuration is present for a domain.</p>
<h4>Basic</h4>
<p>In config.php:</p>
<pre><code><?php
  $domains = array(
    array(
      'domain' => 'myalternatedomain.com',
      'siteurl' => 'http://myalternatedomain.com',
      'home' => 'http://myalternatedomain.com'
    )
  );
?>
</code></pre>
<h4>More Complex</h4>
<p>In config.php:</p>
<pre><code><?php
  $domains = array(
    array(
      'domain' => 'example1.com',
      'siteurl' => 'http://example1.com',
      'home' => 'http://example1.com'
    ),
    array(
      'domain' => 'example2.com',
      'siteurl' => 'http://example2.com',
      'home' => 'http://example2.com',
      'blogname' => 'Example 2'
    ),
    array(
      'domain' => 'example3.com',
      'siteurl' => 'http://example3.com',
      'home' => 'http://example3.com',
      'template' => 'twentyten',
      'blogname' => 'I have a different name...',
      'blogdescription' => '..and description'
    )
  );
?><h3>Tag Usage</h3>
</code></pre>
<p>The provided short codes let you tailor your content per domain if needed. [MultiDomain_else] and [MultiDomain_default] are identical.</p>
<pre><code>[MultiDomain_if domain="example1.com"]
  Content only people visiting on example1.com will see.
[/MultiDomain_if]

[MultiDomain_else]
  Content anyone visiting on any other domain will see.
[/MultiDomain_else]

Normal content everyone will see.
</code></pre>


MultiDomain

Allows multiple domains to be pointed at a single WordPress install with customization for each.
