I went to bestbuy recently for my kid's laptop with issues but still under warranty. The employee asked for a password but my kid is connected with his Microsoft account. I created a 'bestbuy' account on the spot with some classic luggage pin because the employee had no idea what to do. I guess that if my kid went alone, he would have given the ms account password and the employee would have been able to access everything on that account.
