Handling user sessions when using the laravel just for the API and angularJS as a front-end

Hi.

I'm building an app that could be used by both registered users and visitors. What those users could do, is to upload some files. The difference is that guests' files will be stored temporarily. So I'm trying to design a way to handle user sessions.

As you can see in the image I posted below, for the registered users after login JWT will be stored on the browser's local storage and when user's next request is to list his/her files there will be a variable inside the JWT to tell the server where to look for the user's files (which path).

Now for the guests, I thought that I should do something similar but without the login step. For example, when a guest enters to the site, javascript will check if there is a non-expired token on local storage. If that's true, then a random JWT that will point to a temp directory will be created from the server and will be stored onto the browser. But I don't know if this approach is reasonable or if there is any other better approach to do it.

Here is the sketch on how I imagine it.

What do you think? Any ideas or suggestions will be helpful. Thanks.
