Developer Special: Buy one, Get one Free

The WPSSO Core Premium plugin is licensed based on the WordPress Site Address URL (see the WordPress General settings page). Typically, development, staging, and production sites would require 3 licenses, as each uses a different WordPress Site Address URL and each needing Premium features and Premium support.

Note that the .local, .test, .example, .invalid, and .localhost top-level domains are internationally recognized as private use domains – ie. a domain name cannot be registered under these top-level domains. Developers may use these top-level domains for private networks, with custom host files etc., but since these sites cannot be reached from the internet, they cannot be licensed. If you enter an Authentication ID in the SSO > Premium Licenses settings page and activate the WPSSO Update Manager add-on to register the site, the request to register the site’s domain will fail automatically.
