Are you getting a mobile authenticator error message on the Steam Marketplace?
The error message happens when you try to sell an item in your inventory.
It happens after you’ve recently added the Steam Guard Mobile Authenticator.
As a result, you won’t be able to sell any items in your Steam inventory.
In this guide, you’ll learn how to fix “You have not been using the mobile authenticator for 7 days” on the Steam Marketplace.
What does “You have not been using the mobile authenticator for 7 days” mean on Steam?

If Steam says that you have not been using the mobile authenticator for 7 days, it means that you’ve recently added it to your account.
To sell an item on the Steam Marketplace, you must have enabled the Steam Guard Mobile Authenticator for at least 7 days.
If it’s already been 7 days, you must remove and relist the item to sell it.
