Steam Community announcement
reveals Valve's Family Sharing plan now uses
two-factor authorization to allow "lenders more control while reducing the risk
of VAC or other bans resulting from an unknown user accessing and abusing shared
games on an authorized machine" (thanks
). Here's the deal:
We’ve made a change to the way Family
Sharing works in the most recent Steam client beta, where lenders must now
identify the Steam users who may access and play their shared games on shared
computers. This allows lenders more control while reducing the risk of VAC or
other bans resulting from an unknown user accessing and abusing shared games on
an authorized machine.
Family Sharing is now a two-factor authorization process, where up to ten Steam
accounts on up to ten machines may be authorized to share your library at a
given time. Any of these ten users may log into any of your ten authorized
machines to access and play your shared games. Additionally, users may still
request access to your shared library by sending you a request from any machine
where you've installed games.
To authorize up to ten family members to share your games, visit Family Sharing
settings using the most recent Steam client beta update. Our
FAQ have also been updated to reflect these changes.
