Steam Mobile Authenticator is required for skin trades — Steam holds trades for 15 days without it. Set it up via the Steam mobile app (iOS / Android). Takes 5 minutes; instantly speeds up every future trade.
Step-by-step
Install the Steam Mobile app on iOS or Android.
Sign in with your Steam credentials.
Open the menu → Steam Guard → Add Authenticator.
Enter your phone number when prompted; verify with the SMS code.
Steam shows your recovery code — write it down somewhere safe (paper, password manager). You need this if you lose your phone.
Done. Future trade offers can be accepted instantly through the app.
Why does Steam hold trades for 15 days without the mobile authenticator?
Steam's anti-fraud policy. The 15-day hold lets account-takeover victims recover items before they're moved. With the mobile authenticator on for 7+ days, trades complete instantly.
