Question

Jwt security. How secure is it?

I came across a few articles against JWT and the security vulnerabilities it causes. I just wanted to know if it is safe to use and store in local storage or if it should be avoided. Thank you!

Hi @Cameron Hansen,

I take it you are talking about JSON Web Token, is that correct? I can’t say that I would suggest against it. There are security vulnerabilities everywhere in any technology. Let’s take it more broadly, no matter what you pick, you need to make sure everything is up to date and actively patch any APP, service or whatever you want to use. This is regarding everything not only JWT.

Regarding, JWT, they can be either signed, encrypted or both. I think this is safe enough. I mean even if you don’t encrypt it, it doesn’t mean someone can change it as you’ve signed it.
