tried setting up steam family sharing for my brother and ran into a bunch of confusion about what actually transfers and what doesn’t.
the setup process wasn’t obvious and some games just didn’t show up in his library at all. also ran into the thing where if i start playing, he gets kicked out.
for people who’ve used this properly: what’s the actual step-by-step to get it working? and what are the real limitations, not just the marketing version. specifically: which games get excluded, how the simultaneous play restriction works in practice, and whether the new steam families system is different enough to matter.
not looking for the steam support page, looking for someone who’s actually navigated this.
The “only one person can use the library at a time” limitation is the one that surprises people the most. They set up sharing expecting both to play simultaneously and discover that’s not how it works. If both people want to play at the same time, one of them needs to own the game.
Third-party launcher games being excluded is a significant limitation. A lot of the big publishers – EA, Ubisoft, Rockstar – require their own accounts and launchers, which breaks sharing. Effectively the games that share most reliably are from smaller publishers and indie developers who don’t have additional account requirements.
here’s the actual setup and what to expect:
to share your library, both accounts need to be on the same computer at some point. on the computer you want to authorize, log into your account, go to Steam > Settings > Family > enable Family Library Sharing. then the second account logs in on the same machine, goes to Settings > Family > Manage Family Sharing, and authorizes your library.
what sharing actually means: the authorized account can play your games but only when you’re not actively playing. if you launch something while they’re playing, they get a few minutes to save and quit or buy the game themselves. saves are account-specific so progress doesn’t overwrite.
what doesn’t share: games requiring a third-party account (EA App, Ubisoft Connect, Rockstar), games the developer opted out of sharing, and games with DLC complications. this catches a lot of big-publisher titles.
the new Steam Families system (introduced 2024) replaced the old version. up to 6 family members, parental controls, spending approval for minors. if you’re setting this up now you’re using the new system, which is cleaner than the original.
The authorization being per-device rather than per-account for the older system caused confusion. You authorize a computer, not a person – anyone who logs into an authorized computer can access your library. The new Steam Families system is more person-centric which is a clearer model.
the steam families update making this significantly better is worth knowing. the old family sharing system was more limited. the new steam families has proper parental controls, spending approval for minors, and cleaner sharing management. worth setting up from scratch if you’re using the old system.
