Hello! We are excited to announce Steam Families, available today in the Steam Beta Client. Steam Families is a collection of new and existing family-related features. It replaces both Steam Family Sharing and Steam Family View, giving you a single location to manage which games your family can access and when they can play. Create a Steam Family To get started, you can create a Steam Family and then invite up to 5 family members.
I think it’s fair. You should know if your family cheats if you share your games with them
Nah its impossible to always know if they will cheat. It could be their first time.
