Error: “You must enable trade confirmations and the mobile authenticator”

This error occurs if the Steam mobile authenticator is not installed or activated. In such cases, all trades with your account will be delayed by 15 days, complicating the trading process. This is what the buyer sees when requesting your item.

How to Activate the Mobile Authenticator?

  1. Install the “Steam Mobile” app on your smartphone.

  2. Log in to the app using your Steam account.

  3. Activate the authenticator and wait at least 7 days.

This is important because the authenticator will not function fully until the 7-day period has passed.

After this, the error will disappear, and your trades will proceed without delays.
