🚨 Are you using JWTs for authentication? You might be putting your users at risk!

In this comprehensive security deep-dive, we expose the 7 critical flaws in JWT-based authentication that most developers overlook. From token revocation nightmares to XSS vulnerabilities, learn why JWTs might not be the secure solution you think they are.

-------------------------------------------------------------------------------------
🔍 What You'll Learn:
• Why JWT revocation is fundamentally broken
• How JWTs increase your XSS attack surface
• Algorithm confusion attacks and signature vulnerabilities
• Why stateless isn't always better for security
• Secret management complications in distributed systems
• Clock skew issues that can break your auth

-------------------------------------------------------------------------------------
🛡️ Secure Alternatives Covered:
• Server-side sessions with HTTP-only cookies
• Opaque tokens for better security
• PASETO - The JWT successor
• Macaroons for advanced authorization

-------------------------------------------------------------------------------------
🎯 Perfect for:
• Backend developers
• Security engineers
• Full-stack developers
• DevSecOps professionals
• Anyone implementing authentication systems

-------------------------------------------------------------------------------------
⚠️ Disclaimer: This video aims to educate about security risks, not to discourage all JWT usage. JWTs have valid use cases when implemented correctly with proper security considerations.
