If you don’t want to use your camera to sign in, you may authenticate your identity with an “Approve” or “Deny” prompt on the app. While this allows you to avoid inputting a Steam Guard code, you must still provide your account and password. The software will also show you a list of permitted devices, enabling you to remotely sign out of Steam if you left your account signed in on someone else’s PC, find out when it last used your account, or deny access entirely.
The beta version of the app was released by Steam in August. As someone who can never remember their Steam password (and finds Steam Guard codes irritating), this is a wonderful improvement. Steam also says it’s working on bringing its new QR code sign-ins to the Steam Deck and is upgrading its Chat app with “various bug patches,” which will be available for Android today and iOS “soon.”
