You can name them anything you want but the wake word is your problem. You have 3 choices. Computer, echo and alexa. Custom wake words would be great!!!!!
I know if you have a lot of echo's you can name them for a wake up so then don't get confused on which one you want? I just forgot where the info is at so I can do just that? Does anyone know?
Change your wake word on your phone app - open app>menu (the little mostly hamburger thing on the top left)>choose a device, and scroll down to the wake word>tap wake word and choose the one you want to use with that device. Choices are "Alexa", "Amazon", "Echo", and "Computer"
They really need to give us more options or make them completely customizable...
