SSO can exist without federation (like Kerberos on a local network), and federation can exist without SSO (requiring re-authentication each time). Modern federated systems use protocols like SAML and OpenID Connect to establish cryptographic trust between identity providers and applications. The key distinction matters for system design: centralized SSO within one organization is simpler to manage, while federated identity across organizations requires explicit trust relationships and makes challenges like global logout significantly harder. ## Full article daily.dev links to this article rather than hosting it.
