Creating a new account for a specific Device

[jordannabigon]

We just got a Google Home, and I set Spotify (we have Spotify Premium for Family) up with it, but if I'm at work playing music, and my fiancee starts using it, it cuts my music off. We could set her account up, but the same would happen to her when I go to use it. I tried creating a 2nd account for myself just to use on Google Home, but Spotify won't let me. I've been trying to use Spotify Help, but I find it incredibly unhelpful. Anyone have any suggestions?
