What is Steam Guard and Why Do I Need It?

Steam Guard is a security feature provided by Steam that helps protect your account from unauthorized access and fraudulent trades. It requires you to provide a verification code from your mobile device or email when logging into your account or performing sensitive actions, such as sending or accepting trade offers. Enabling Steam Guard Mobile Authenticator for at least 15 days is a mandatory requirement for selling items on our platform, as it helps ensure the security of your account and prevents unauthorized trades.
