@freemo thanks. I was only asking about services on the same domain, for an instance like qoto.org.
sharing log-ins across domains/service providers is quite a leap, I only recently felt that I understood how Hubzilla's "nomadic" identity/OpenWebAuth works and it wasn't how I thought it works earlier.
That does suggest that free/open software developers could collaborate more. Hubzilla (and Friendica, and Diaspora) still have, say, their own events and calendars and photo album support, and Mastodon (and Mobilizon, and Pixelfed) have their own auth.
@tetrislife if by same domain you mean to include subdomains then the issues I raised are still relevant. They are relevant tot he qoto services since each one is a separate app and not all of them integrate with SAML
