I’d like to have an automatic user id for every user connected to my app whether they have registered for a user account or not. I suppose I can just use a uuid and store it in a session, but I was wondering if there is a way to do something more like a session user, where the user is given a full user account id, which would be merged/migrated to their actual user if/when the log in. I don’t actually need the second part for now.
