I'm a hacker, pretty much in the old school sense of the word. But I do know IT security too.

      Agree about JWTs, but stateless auth is the default configuration of ASP dot NET. Do you think people should turn that off and use a non-default configuration?

      We're using stateless auth in a system with tight SLAs and hundreds of millions of users. Fetching the state from some database would break the latency budget.

      I’m not so much doubting you as observing that it’s likely that bigger places than yours have scaled serverside stateful auth (given latency budget).

      We're one of the biggest AWS customers, the list of bigger places than us is very short. I maintain that managing latency is a reasonable tradeoff for stateless authentication. We're working on making most of the services stateless, well beyond just authentication aspects.

          I think I’d just say “stateless auth is not a good place to start at”.

          You might be right about that. It might be a place you end at, though, and there might be reasons. Heck, we're running a dozen different services, each run by a different team. Loose coupling between AAA and the service is a good enough reason in itself.

          Inter-service stateless auth makes a lot of sense to me! It’s the value of pushing that design out to the client where I start to dislike it.

          … it helps that inter-service stateless auth is also _much easier_ than clientside stateless auth.

          And I'm *so glad* I only have to audit auth flow for one team (including password recovery and all the pitfalls), instead of all of them!
