MFA, IAM Identity Center, Federation, and Cognito | AWS CLF-C02 Mastery

Learn to pick the right AWS identity service for any scenario: MFA for security, IAM Identity Center for workforce SSO, federation for corporate directories, and Cognito for end-user applications. This hands-on tutorial covers the critical distinctions that prevent the most common identity mistakes on real-world AWS projects and the CLF-C02 exam. This video walks you through the identity decision tree that consultants and architects rely on daily. You'll understand when to use each service, why they exist separately, and how they fit together in multi-account, multi-tenant environments like CodeGorillas' 40-account setup.
