Steam Families replaced the old library-sharing system in September 2024. The old Family Library Sharing system, the one with authorized computers and a library that locked up the moment its owner launched anything, is gone. Valve replaced it with Steam Families, announced in beta on March 18, 2024 and rolled out to everyone on September 11, 2024. Its membership rules include a hard six-member cap, one-year cooldowns on leaving, a region check, and a VAC policy that can get the game owner banned for someone else’s cheating.

What changed: old Family Sharing vs Steam Families

Valve’s FAQ and launch announcements describe these differences:

MechanicOld Family Library Sharing (2013-2024)Steam Families (current)
StructurePer-device authorization (specific computers)Account-based family group, up to 6 members
Library access while owner playsEntire library locked when the owner played anythingMembers keep playing other games from the same library
ConcurrencyOne borrower at a time for the whole libraryOne player per owned copy, per game
Achievements and savesBorrower’s ownEach member gets their own saves and achievements
Parental controlsSeparate system (Family View, PIN-based)Built in, per child account, managed remotely
Child purchasesNot supportedPurchase requests: child fills a cart, an adult approves and pays
LeavingDeauthorize anytimeOne-year cooldown before joining or creating another family

The single biggest upgrade is the concurrency model. Under the old system, if the owner launched anything, the borrower got a few minutes to buy the game or quit. Under Steam Families, the shared pool works per copy: your brother can play your copy of Baldur’s Gate 3 while you play your own copy of Elden Ring, at the same time, from the same library.

Membership and shared games

Six members, adults and children. A Steam Family holds up to six accounts. Each member is either an adult or a child. Adults can invite and remove members, manage parental controls, and approve purchase requests. Children play what they are given access to and cannot leave the family on their own; an adult (or Steam Support) has to remove them.

One library pool. Every member’s shareable games merge into a single family library. Members see each other’s games in their own library view, install them, and play with their own saves and achievements.

One player per copy. Any number of members can play different games from the pool simultaneously. Two members can only play the same game at the same time if the family owns two copies of it. Buying a second copy inside the family is the intended solution, and Valve says so explicitly in the FAQ.

Same country. Steam Families is designed for one household. All members should be in the same country as the person who created the family, and Steam checks store regions when someone tries to join. Cross-border families fail at the invite step.

Sharing keeps working while the owner plays. The owner playing one game no longer blocks the rest of their library. This was the headline feature at launch.

Cooldowns when changing families

Changing families can trigger a cooldown for your account and for the vacated member slot:

ActionCooldown
Adult leaves (or is removed from) a familyCannot create or join a new family until 1 year after they joined the previous one
A member slot is vacatedThat slot stays locked for 1 year before a new person can fill it
Rejoining your most recent familyNo cooldown, as long as it still has a free slot
Child wants to leaveNo self-service; an adult removes them, or Steam Support does

Check the account and slot cooldowns before changing membership. Leaving a family or removing someone can prevent you from immediately joining another family or inviting a replacement.

How to set up a Steam Family

The whole process takes about five minutes if everyone is in the same country and reachable.

  1. Update Steam on your main account, then open Steam > Settings > Family.
  2. Click Create a Family and name it. You become the first adult member.
  3. Invite members. You can invite from your friends list or by sending an invite link. If you only know someone’s profile URL or vanity name, resolve it to their account with our Steam ID Finder first and add them as a friend.
  4. Each invitee accepts from the notification in their client, on mobile, or in the browser. When inviting, you choose whether they join as an adult or a child.
  5. Done. Shareable games from every member appear in everyone’s library under the family filter. There is no per-computer authorization step anymore; sign in anywhere, including a Steam Deck, and the shared library follows the account.

For child accounts, go to Settings > Family > [child’s name] and set parental controls: which games from the family library they can see and launch, daily playtime limits, store and community access, and whether they can send purchase and playtime requests. Adults approve those requests from the Steam mobile app or email, pay with their own payment method, and the game lands in the child’s account.

Before combining libraries, use the Steam Calculator to compare their size and value. Members do not need to own equal numbers of games.

What cannot be shared

Not everything in a library enters the family pool. These categories have sharing restrictions:

  • Free-to-play games. There is nothing to share; everyone already has access. CS2 falls in this bucket, which matters for the VAC discussion below. Deadlock, likewise free, is also outside the sharing system (our Deadlock beginner’s guide covers that game separately).
  • Games that require a third-party account or launcher, such as titles tied to EA App, Ubisoft Connect, or Rockstar’s launcher. The Steam license shares, the third-party entitlement does not, so Valve excludes them.
  • Games whose developers opted out of family sharing. There is no master list; the game simply will not appear in the family library.
  • DLC, partially. You borrow a copy as-is: base game plus whatever DLC its owner bought. What you cannot do is own the base game yourself and borrow only someone else’s DLC for it.
  • Non-game licenses like software, and anything region-restricted in a way that conflicts with a member’s store country.

If a game is missing, check whether its developer allows sharing and whether it requires a separate account.

VAC bans in shared games

Under Steam Families, if a family member cheats in a shared game and gets VAC banned, both the cheater’s account and the account that owns that copy get banned. The ban attaches to the accounts, not to the family, and it works exactly like a ban earned solo: permanent, not appealable.

The boundaries of the rule, as clarified by Valve staff in the Steam Families group:

  • Pre-existing VAC bans do not spread. Adding someone who was banned years ago does not infect the family.
  • Only the playing account and the copy-owning account are hit. Other members are untouched.
  • This sharing rule does not apply to free-to-play games. Since CS2 cannot be shared, a CS2 cheater in your family gets only themselves banned. Their inventory still gets frozen, though, which is one more reason the market treats banned accounts as dead weight; see our guide on cashing out CS2 skins for why locked inventories matter, and the case odds breakdown if the skins themselves are the family’s shared hobby.

Only share your library with household members you trust to play without cheats. Their use of your copy can affect your account.

Steam Deck, saves, and day-to-day use

Steam Families is fully account-based, so it behaves well on secondary devices. A family member’s Deck sees the shared library the same way their desktop does, and Steam Cloud keeps each member’s saves separate per account. If your household bought a Deck partly to make the shared library portable, our Steam Deck picks for 2026 is built around exactly that use case, including which heavy games are worth installing on a 512 GB card.

Offline play works with borrowed games, with the usual caveat that games requiring third-party servers still need a connection. If a launch fails and you suspect Steam itself rather than the family setup, check Is Steam Down or the full server status page before you start reinstalling things.

Troubleshooting

Check the error message against these common causes:

SymptomLikely causeFix
Invite fails or the join button errorsInvitee’s store country differs from the family creator’sAll members need matching regions; there is no workaround short of a legitimate country change after moving
”Create a Family” is missing or greyed outYou are inside another family’s cooldown windowWait out the 1-year timer from when you joined the previous family, or rejoin that same family
A specific game is not in the family libraryDeveloper opt-out, F2P title, or third-party account requirementNothing to fix; check the game’s store page for the family sharing note
”This game is currently unavailable” at launchAll owned copies of that specific game are in useWait, ask the other player to quit, or buy a second copy; other games in the library remain playable
Shared games vanished for one memberThey were removed from the family, or a family member’s account has a restrictionCheck Settings > Family membership status on both ends
Child cannot buy anythingWorking as intendedThe child sends a purchase request; an adult approves and pays from the mobile app or email
New member cannot be added after someone leftVacated slot is on its 1-year cooldownWait for the slot timer; the returning member themselves can rejoin without penalty
Games launch but progress is shared or missingSigned into the wrong account on a shared PCEach member must use their own account; saves and achievements are per-member by design

If the library has not updated after a membership change, restart Steam on both accounts to refresh its local state.

Is it worth setting up?

Steam Families lets household members share eligible games, manage parental controls and approve children’s purchase requests. You still need a copy for each person playing the same game at once, unless that game provides another option such as a guest pass. Check the seasonal sales before buying extra copies.

The household requirement, membership cooldowns and VAC rules are the main limits to consider before joining. You can gauge how big the combined pool gets with the Steam Calculator, check what the family is actually playing via player counts and charts, and browse the rest of our Steam guides for more account and library guides.
