Subdomain Authentication

With the Domain Mapping System plugin, you can now let users login to subdomains and navigate protected pages.

In order to allow website visitors to login to user accounts on mapped subdomains of your website, you can simply enable the checkbox for Subdomain Authentication:

Subdomain Authentication Checkbox

This will allow users to login to Subdomains of your website and remain only logged in to that subdomain. They are only able to access protected login pages that are mapped to the specified subdomain.

Only subdomains that are a derivative of your site's base domain are supported. For example, if your base domain is site-domain.com, you can allow users to login on any variation of *.site-domain.com, such as account.site-domain.com.

Selective Subdomain Authentication

The dropdown checkbox allows you to selectively activate Subdomain Authentication only on specific subdomains:

Activating Subdomain Authentication on Specific Subdomains

We hope to have full Alias domain authentication supported soon, but that will require 3rd party OAuth integration of some kind and may take some time to develop. Subdomains of an Alias domain are not supported yet. Please contact our team for updates or to request integration with a specific OAuth platform.

WooCommerce Subdomain Authentication

To allow login to protected WooCommerce areas, such as the Account area, there is another checkbox to activate for that. These can be activated independently from each other, if you only want to allow WooCommerce authentication, for example.

Multisite Requirements

If you are trying to configure Subdomain Authentication on multisite, you must update the sunrise.php file mentioned in our multisite integration docs to change this string from this:

if ( ! is_multisite() || $is_admin ) {
    return $site;
}

To this:

if ( ! is_multisite() || ! $is_admin ) {
    return $site;
}
