AUTHENTICATION & AUTHORIZATION EVOLUTION | Complete History Explained

Ever wondered how we went from storing passwords in every app to modern OAuth 2.0 and OpenID Connect? This video breaks down the entire evolution of authentication and authorization in just minutes!

📚 WHAT YOU'LL LEARN:

✅ Phase 1: The Basics - Why multiple passwords became a nightmare
✅ Phase 2: Directories (Active Directory) - Centralized identity management
✅ Phase 3: SAML - Cross-domain SSO across company boundaries
✅ Phase 4: OAuth 2.0 - Solving the password sharing anti-pattern
✅ Phase 5: OpenID Connect (OIDC) - Standardized authentication layer
✅ Phase 6: PKCE - Securing mobile and native apps

🎯 KEY CONCEPTS COVERED:

• The "Password Sharing Anti-Pattern" and why it's dangerous
• Difference between Authentication vs Authorization
• Security Tokens vs Access Tokens vs ID Tokens
• The Confused Deputy Attack and how OIDC prevents it
• Why mobile apps need PKCE (Proof Key for Code Exchange)
• How modern SSO actually works under the hood

💡 PERFECT FOR:

→ Software Engineers & Developers
→ Security Professionals & InfoSec Teams
→ System Architects
→ DevOps Engineers
→ Computer Science Students
→ Anyone preparing for Security Certifications

📖 FROM THIS VIDEO YOU'LL UNDERSTAND:

• Why each technology was created and what problem it solved
• The security vulnerabilities that drove each evolution
• Real-world examples (like LinkedIn asking for Gmail passwords)
• The conceptual journey from implicit trust to explicit proof
• How modern apps like mobile applications stay secure

🎓 CONCEPTUAL SHIFTS EXPLAINED:

1️⃣ Implicit Trust → Explicit Scope: From sharing full passwords to granting specific, limited permissions
2️⃣ Delegation → Authentication: From "access to resources" to "proving who you are"
3️⃣ Static Secret → Dynamic Proof: From permanent client secrets to per-request verification
