Multiple Accounts on Deck?

Hey Folks,

I‘m planning to buy a Deck next week and wondered If you can have Multiple Steam Accounts on one Device.

My thinking was to put my account on there (for savegame from PC) + Create one for my Wife to Family share my games so we can play games together (One on PC, one on deck)

I know I can figure it out once the deck is here but my curiosity doesn’t leave me alone 😂
