Allowed Email Domains gives administrators a simple way to restrict WordPress user accounts to approved email domains.
The plugin is designed for sites where only users from specific organizations, companies, clients, or teams should be added as WordPress users.
Features include:
<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>
The plugin includes:
<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>
Recommended operational practices:
<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>
Deleting the plugin removes its current options:
<ul>
<li><code>pageauth_allowed_domains</code></li>
<li><code>pageauth_audit_log</code></li>
<li><code>pageauth_block_unauthorized_logins</code></li>
</ul>
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.

Important: This plugin has a new maintainer. So the plugin will now be active developed again, and it’s now part of <a href="https://goinput.de" rel="nofollow ugc">goINPUT</a>.
Multiple Domain allows you having more than one domain in a single WordPress installation. This plugin doesn’t support 
more than one theme or advanced customizations for each domain. It’s only intended to enable constant navigation under 
many domains. For a more complex setup, there is 
<a href="https://codex.wordpress.org/Create_A_Network" rel="nofollow ugc">WordPress Multisite (MU)</a>.
When there is more than one domain set in your host, all links and resources will point to the default domain. This is 
the default WordPress behavior. With Multiple Domain installed and properly configured, it’ll update all link on the 
fly. This way, the user navigation will be end-to-end under the same domain.
You can also set an optional base URL. If you want only a set of URL’s available under a given domain, you can use this 
restriction.
Additionally, a language can be set for each domain. The language will be used to add <code><link></code> tags with <code>hreflang</code> 
attribute to document head. This is for SEO purposes.

Multiple Domain

Hello,

Does this plugin work on multisite installation?

For example, if I appoint both abc.com & def.com to the same wp multisite installation, then

Main site: 
  abc.com = def.com
Sub sites:
  123.abc.com = 123.def.com
  456.abc.com = 456.def.com
  ...

Something like this.

Thanks in advance.





Is it multisite compatible?

There are time, you would wish to maintain a seperate domain/subdomain for Dashboard area to securely access. This plugin let you access while properly rewriting internal links to selected domain. The author of this plugin is highly responsive. Thank you so much.

Really helpfull plugin and great for SEO too.

Great


Having a staging page separated from production, but in the end with same databases, switching to that staging site without being redirected back to a production URL is a total lifesaver!


Saving a lot of frustration

This plugin allows you to have multiple domains in a single Wordpress installation and enables custom redirects for each domain.
