Visting sites that SSO with the same Zitadel instance
If a customer logs in from one site, can they seamlessly go between multiple sites using the same Zitadel instance for SSO without having to log in again?

I think Clerk refers to this as "satellite domains".
hey @rybodium if all the sites share the same top-level domain (like site1.example.com and site2.example.com), Zitadel can do SSO automatically using cookies.

What if they don't have the same TLD?
hey @rybodium even with different TLDs, your users can still enjoy "near‑seamless" SSO if you enable domain discovery and verify each domain under the respective org and you map custom domains (e.g. app1.com, app2.net) under the same instance.
We're trying to use Zitadel as a B2C CIAM so I don't think domain discovery applies. Most of our customers have gmail addresses.
