Identity and Access Management (IAM) is the invisible engine behind every secure login — from GitHub to Google Workspace to AWS. But how does it all really work? In this video, we break IAM down into clear, digestible parts: - What is IAM? (Identity + Access Control) - How Identity Providers (IdPs) authenticate users - How Federation enables Single Sign-On (SSO) - The difference between AuthN and AuthZ - Why protocols like OAuth, SAML, and SCIM matter - How companies use AWS IAM + Okta + custom flows - Real-world architecture diagrams and role-based access in action Whether you're building apps or auditing systems, this video will give you a solid grasp of how IAM works — from login to permissions. 🔐 Don’t forget to explore the full System Design & Security playlist on this channel! ⏱️ Timestamps 0:00 – Intro: What IAM Solves 0:40 – What is IAM?
