Share your library of games with Steam Family Sharing
Steam Family Sharing is now available to all users.
Steam Family Sharing, a feature that allows friends and family to share their libraries of Steam games, is now available to all users, Valve has announced.
A user can make his library of Steam games available for others to access, download, and play on approved authorized accounts and devices. You may authorize Family Library Sharing on up to 10 devices at a given time, and for up to five accounts. Though simultaneous usage of an account is prohibited, the lender is always able to play their games at any time. If the player decides to start playing while a friend is borrowing a game, the friend will be given a "few minutes" to purchase the game or quit.
Individual members can earn their own achievements and keep their own saves and application data intact with Steam Cloud.
Lenders can’t access games that aren't available in their region or games that require a third-party key, account or subscription.
You should also be careful about who you share with. Family sharing privileges may be revoked and your account may be VAC (Valve’s anti-cheat system) banned if your library is used by others to cheat.
You can find out more about Family Sharing and instruction on how to use the feature on Steam’s website.
