Steam now requires the highest level of account security for instant trades
As of Dec 9, to trade away items instantly you’ll need: a Steam Guard Mobile Authenticator enabled on your account for at least 7 days and trade/market confirmations enabled. Otherwise, to give you time to stop a trade if your account is compromised, items will be held by Steam for 3 days before delivery.
Now you can confirm trades and market sales through the Steam Mobile App. Ensure items never leave your account without your approval.FAQ
