I am thinking of placing Amazon Echo devices to monitoring rooms where people monitor different processes. With a skill people can ask Echo to tell about a certain metric etc.
The thing is that many different people would be using the same systems, so authentication would have to be done based on device identity. There are multiple monitoring rooms, each room monitoring different processes.
My question is that what is the right way to do authentication without compromising Amazon account rules etc. Should I just make one Amazon account that the skill is attached to and then the skill would vary results based on device id?
