Session vs JWT — the debate is finally OVER #Shorts

When should you use server-side sessions instead of JWT?

A) Never — JWT is always better
B) When you need instant token revocation
C) Only for legacy applications

📌 The answer: B — When you need instant token revocation

🧠 WHY THIS MATTERS
Server-side sessions are superior when you need to immediately revoke access — banning a user, forced logout, password change invalidation. With sessions, you delete the session record and the user is instantly locked out. With JWT, the user keeps access until the token expires. GitHub uses server-side sessions for exactly this reason. When they detect a compromised account, they need instant revocation, not "wait 15 minutes."

⚡ THE TWIST
The industry swung too hard toward JWT. For most web applications, server-side sessions with Redis are simpler, more secure, and perform just as well. JWT makes sense for microservices and API-to-API communication, not for user login sessions.
