What happens if two people want to play at once
Family Sharing only allows one person to play a shared game at a time. If the library owner starts playing a game that someone else borrowed, Steam gives the borrower a short warning window to either buy the game or stop playing before it closes automatically, so timing matters if you're sharing with an active household.
Achievements, saves, and DLC generally carry over
Borrowed games keep their own achievement progress and cloud saves tied to the borrowing account, and most owned DLC is included automatically. Some games with third-party anti-cheat systems or that require a separate account link are exceptions and may not support shared play at all, so it's worth checking a title's store page if sharing doesn't work as expected.
Frequently Asked Questions
Can I share my library with more than one person?
Yes, Steam allows authorizing multiple family members, though only one shared game can be played from your library at any given moment across all of them.
Can I get a refund for a game I only played through Family Sharing?
No. A refund can only be requested by the account that actually owns the game; time played through Family Sharing on a borrowing account still counts toward that owner's normal refund eligibility window.
