Want to let your friends or family experience your epic Steam library without giving away your precious account? Steam Family Sharing is the answer! It's a safe and easy way to share your games with up to five other accounts.
Here's the lowdown: First, enable Steam Guard on your account for added security. Then, authorize the other computers you want to share with. This requires logging into your Steam account on their device. Go to Steam Settings > Family, and check the 'Authorize Library Sharing on this Computer' box. Select the accounts you want to share with. That's it!
Keep in mind only one person can play from your library at a time. If you, the game owner, decide to play, the other person gets a few minutes to save their progress before being booted. So, coordinate your playtime and spread the gaming joy!
