We're getting way way beyond the purpose of my article, but let's cover it quickly.

I see there are maybe some conceptual confusions.

When sets a cookie, it doesn't need to be available for When fires a subsequent request to API, the cookie will be sent along with it. It's the API that needs the JWT, not This can work if you set the API to accept CORS.

What I mean is that a session uses a cookie the same way its proposed for JWT to use it. Obviously they are different implementations.

The problem with sessions is not encryption, but what can be extracted from them. JWT can store minimal user object, so that API doesn't necessarily have to reach a database for that.
