A Device ID would not in general be unique either because it would be managed
by the users browser software which could have features to change the ID, or
open a window with a new ID, or export the ID, etc.  It's not your computer so
not your choice.

You could issue users with a controlled device that you own and under restrictive
contractual terms and proxy authorization through this.  Or perhaps limit service
to devices with an ID that is not trivial for users to change.
