SAML vs OIDC: Choosing the Right Protocol for Modern Single Sign-On

This post compares SAML and OpenID Connect (OIDC) for modern enterprise single sign-on, describing technical differences (XML/SAML vs JSON/JWT), transport and mobile suitability, and typical use cases—SAML for legacy or highly regulated environments and OIDC for mobile and API-first applications. It calls out implementation and security pitfalls (XML signature wrapping, redirect URI validation, timestamp/clock skew), and recommends using identity brokers (e.g., SSOJet) to simplify integration and reduce risk.
