JWT 和一次性代币? [英] JWT and one-time tokens?

问题描述

I'm in the process of rolling my own JWT token auth, however, I would really like it to be a one time-token – so once it's used, the server generates a new token and the client will have to use that token during the next request/call.

However, it has come to my understanding that JWT is supposed to be 'stateless' – but with the approach of a one time token, I guess I would need to somehow store the valid tokens, since the token will be refreshed once it's used. Or is there any way to avoid storing a value on the server, and still be able to create one-time tokens?

The two main reasons for why I don't want to store any value is first of all scalability (sure, I could have cache-server inbetween to store the values, but it would be nice if that wasn't required), secondly, JWT is supposed to be stateless from my understanding, which it wouldn't be if I need to store a value on the server to be able to validate the token.

Any ideas?

解决方案

Use the user's current password's hash for signing the JWT token, in this way all tokens generated before a successful password change would get invalidated the next time. I got the idea from here https://www.jbspeakr.cc/howto-single-use-jwt/.
