Steam
Steam is a platform for PC games, created by Valve. Originally developed for Windows Operating Systems it nowadays supports MacOS X and Linux as well, although not all titles are playable on the latter two.

Family Sharing
With Steam it is possible to share one's library of games with family members. To do so, you have to login at least once on the same computer with each account, the one who shares his library as well as the one that gets the permission to use it. Then, log in with the account that owns the games you want to share and click on "Steam", then on "Settings". In the "Account" tab check that Steam Guard is enabled, then change to the "Family" tab. Here click on "Authorise this computer" and check the other user account below.
To use the games shared, login with the second account and equally check that Steam Guard is enabled. The first account's library should automatically be added.
While this enables a family member (or friend) to play a game from the library, only one person can play the game at a time. Moreover, the original owner can start playing a game any time; if this game is currently in use by a different family member, he or she will be kicked from the game (after receiving a warning that the current game should be saved as soon as possible).
