TL;DR: OIDC is lighter and easier to implement, but SAML still dominates complex enterprise federation because it carries richer assertions, supports hub-and-spoke trust, and better fits compliance-heavy SSO environments, according to WorkOS. The practical issue is not protocol preference but whether your identity programme can preserve auditability, federation scale, and legacy application compatibility.
Editorial analysis by NHI Mgmt Group, based on content published by WorkOS: “OIDC vs SAML: How a two-decade-old protocol still dominates identity federation”.
Key questions
Q: How should security teams choose between SAML and OIDC?
A: Choose SAML when you need mature enterprise federation for browser-based applications and central assertion handling.
Q: Why does SAML still work better for some regulated identity environments?
A: SAML is better aligned to regulated environments when identity events need to be cryptographically verifiable and richly contextual.
Q: What breaks when organisations try to replace SAML too quickly?
A: What usually breaks is not login alone.
Practitioner guidance
- Map applications by federation complexity Separate legacy, compliance-heavy, and multi-party federation dependencies from modern app-only integrations before choosing a protocol path.
- Preserve SAML where rich assertions matter Keep SAML in place for workloads that rely on hierarchical attributes, authentication context, or explicit federation trust relationships.
- Standardise OIDC for modern app patterns Use OIDC where the application estate is API-first, client-specific, and does not depend on SAML-style metadata exchange.
Bottom line: SAML persists because enterprise federation still depends on rich assertions, scalable trust relationships, and audit-friendly identity context.

Protocol choice is now a federation governance decision, not a developer convenience decision. WorkOS correctly shows that the SAML versus OIDC question persists because enterprise identity is still shaped by trust topology, legacy application requirements, and audit expectations. That means IAM teams should evaluate protocol support as part of programme architecture, not as a front-end integration preference. The real constraint is whether the identity model can still express trust at enterprise scale.
A question worth separating out:
Q: What is the difference between hub-and-spoke federation and app-centric trust?
A: Hub-and-spoke federation lets one identity provider manage trust across many service providers through shared metadata and repeatable onboarding. App-centric trust configures each client relationship separately, which is simpler for one app but harder to scale across a broad enterprise estate. The difference is scale of governance, not just protocol syntax.
