Federated Identity vs Single Sign-On (SSO) | Stop Confusing IAM Architecture

Are you confused about the difference between Federated Identity and Single Sign-On (SSO)? You’re not alone. While both deal with authentication and access control, they solve fundamentally different architectural challenges. In this video, we break down Federated Identity vs. SSO with real-world developer examples, protocol overviews (SAML, OAuth, OIDC), and clear diagrams so you can design secure identity systems with confidence. *💡 What You'll Learn* - The core technical definitions of SSO and Federated Identity - Key differences: Single domain vs. Cross-domain trust relationships - How identity providers (IdPs) operate across enterprise boundaries - Real-world protocols: SAML, OpenID Connect (OIDC), and OAuth 2.0 - When to implement SSO vs. when you actually need Federation *Chapters* 0:00 - The Confused Developer (Intro) 0:45 - What exactly is Single Sign-On (SSO)? 2:30 - What is Federated Identity? 4:15 - Core Differences (Architectural Breakdown) 6:00 - Real-World Use Cases: Which should you choose? 7:30 - Next Steps & Resources Read the full blog post by Andrea Chiarelli: https://auth0.com/blog/federated-identity-vs-single-sign-on-key-differences/ #FederatedIdentity #SSO #IdentityManagement #Cybersecurity #SoftwareArchitecture If you enjoy this content and want to learn more about identity, security, and access management, subscribe to our channel!
