Single Sign On For TNG improves the user experience when WordPress and the TNG Genealogy Software are on the same or different servers. User accounts for both systems are managed through the WordPress user registration system. This includes account creation, deletion and password change. Logging in and out of the users WordPress account automatically logs in and out of their account in TNG. This plugin makes no attempt to visually incorporate TNG into the WordPress theme. But TNG’s template feature allows the developer to design a visual for TNG which is consistent with that of the WordPress Site.
