If you are an active Steam player, then you are familiar with Steam Guard. Its task is to protect the account from hacking, as well as from unauthorized trading of items on a virtual trading platform. To use this mechanism, you need a portable device with an iOS or Android operating system. We need to put the mobile client of the corresponding gaming platform on it, to which all the Steam Guard confirmation codes will come. For owners of smartphones and tablets based on Windows and other operating systems, installing Steam Desktop Authenticator https://steamauthenticator.net/ will help.
