Is it possible to use a single identity provider with multiple Genesys Cloud orgs?
Yes. To use a single identity provider with multiple orgs, repeat the steps you followed when configuring your first single sign-on integration. As you do, make sure that there is a unique Relying Issuer URI for each one. This allows the identity provider to distinguish which organization initiated the request.
