Users on multiple Gramps Web sites currently need separate logins for each instance. The “too many logins and registrations to track” could start to aggravate users as they begin to discover more Gramps Web sites.
Discourse Meta realized the value of cross-site community building by adding themselves as an OIDC (OpenID Connect) provider, enabling users to log into any Discourse forum using their Meta account—encouraging collaboration and pollination between forums.
Gramps Web could extend its existing OIDC support for external logins (Google, GitHub) to let instances act as identity providers in the same way. Users pick one “home” site, log in once via Single Sign-On (SSO), and access others without new accounts. External services like FamilySearch or WikiTree could follow later.
Admins would gain easier cross-site collaboration, tree sharing, and community building between instances—increased engagement without a central hub.
Adding rudimentary Gramps Web sites catalog to GrampsHub could aid discovery of related instances.
