Did a quick web search. Might have something to do with Spotify. Seems that for the ability to control Spotify via the Spotify app you have to register your Sonos products to Spotify.
So if this was activated by the customer then installing a new playbar might auto trigger the need to register that device into the account thus requiring the need for the Spotify user name and password.
