Yeah this is the problem with crypto security people they are one dimensional. JWT has the benefit of allowing disconnected services to send each other information through the front end.

Which minimizess the number of things you need to get right or in your words equals more secure.

Designing a token that can be validated instead of looked up. (Design/Implement once)

Or

maintaining, updating and monitoring a set of firewall rules so that app-servers in network zone x and y can make call backs to a database in network zone z.(design many implement many)

There are a ton of great reasons to use JWT at scale. As with anything use case is important.

I disagree almost absolutely with all of this but am comfortable with how persuasive our respective comments on this thread are or aren't to the rest of HN. I'd rather not re-make points I've already made.

That's also an argument for just using Kerberos over the Internet. And I'm not sure that's a good idea.

I'm almost certain it's a bad idea if that means rolling your own Kerberos implementations in php, javascript and golang in order for your various back-end to speak to your various front-ends.

But sure, leverage secret-key crypto and tickets in your own implementation in a way that's more secure than Kerberos.

Or, use a solution that's simple enough any weakness is fairly obvious.
