Spotify Connect password protection?

[StupidRoommates]

I have a lovely setup with a Denon AV receiver, which has Spotify Connect, with which I can effortlessly to the tunes I want. However, a few days ago my roommate, who also has Spotify premium, figured out she can also use my Spotify connect, which results in things such as "I Just Had Sex" and "Sexual Healing" at unconvenient times. Of course, I can have my share of laughs about this, but if there is a way of preventing her from doing this every time, such as a password or the likes, that'd be very welcome. Is there a way to set this up?

Do you have a solution for this problem?
