JWT and server side token storage -

-

every article i've read vouching advantages of jwt state 1 of these advantages ability auth system distributed across multiple servers. i.e . aren't relying on central repository of user auth details lookup on every request.

however when comes implementation, i've read in many places added security shouldn't rely on jwt signature verification itself, , should maintain list of black or white list tokens generated server.

doesn't defeat advantage i've listed above, list of tokens need stored centrally servers can access , require lookup on each request?

how have people implemented on end?

you making points in question. make sense store oauth token @ central location in order make easier implement signout/revoke functionality. if relied on token signature couldn't have possibly implemented such feature. suppose user wanted revoke access token. in case if didn't have central location/datastore tokens have invalidated , relied on token signature, token still have been valid.

so indeed, when want build more advanced systems dependent on oauth tokens, central store tokens more must.
