With IPBWI for WordPress v4, you will get flawless Single Sign On.
How does SSO work?
IP.board brings a SSO API which allows to add several "slaves" as satellites to a "master" IP.board installation. This results in a robust single sign on solution allowing unlimited slaves even on completely different domains - same origin policy which normally breaks setting cookies for different domains has been bypassed here successfully.
WordPress 4.9 or higher
IPcore/IP.board 4.2 or higher
While this software might run on configurations with older versions, we always develop, test and support for most current versions only.
