Steam’s account borrow request feature allows you to share your game library with friends and family members. This can be useful if you want someone to try out a game before they buy it, or if you’re going on vacation and want someone to take care of your account while you’re away.
To enable account borrow requests, you’ll need to first create a Steam Family Sharing group. Once you’ve created a group, you can invite other Steam users to join. Once they’ve accepted your invitation, they’ll be able to request access to your game library.
