<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>
