User A has a favorite list added by user A
If user B logs in on the same device
All the favorite lists from user A are transferred to B
The favorite list in user A disappears and is deleted
The same problem if any user logs in from the administrator control panel
The favorite list is transferred to every user selected from the administrator control panel
The problem is related to the session stored in Local Storage

We might need to shuffle ID once user loggout I think.
