JWT vs Session Tokens | What's the Difference and Which Should You Use?

The article compares session-based auth and JWT-based auth in web apps.

Sessions store state on the server, making logout and token revocation straightforward.

JWTs store state on the client, which improves stateless scalability but makes invalidation harder.

The tradeoffs affect security, database load, and fit for browsers, mobile apps, and microservices.

It also notes that tools like Supabase, Clerk, Firebase, and NextAuth do not all default to the same auth model.
