Steam keys can be shared until they are redeemed. If you receive a Steam key through a purchase or a crowdfunding reward, you’re welcome to provide that key to a friend or redeem it on a different Steam account as long as it hasn’t been redeemed.

Once a key is redeemed, we have no way of transferring the content to another account, so please double-check which Steam account you are using before redeeming a key.

For more information on how to redeem Steam keys, please visit this Steam help article.
