The Steam Guard Mobile Authenticator is a feature of the Steam Mobile App that provides the highest level of security to your Steam account. It gives you multiple options to quickly and easily sign in to Steam, while ensuring no one else can access your account.

At sign in, you can scan a Steam QR code, rather than typing in your account name, password, and Steam Guard code. Alternatively you can enter your account credentials and confirm it's you with a single tap in the app.

If you are having trouble using the Steam Guard Mobile Authenticator, please review our Steam Guard Mobile Authenticator FAQ for troubleshooting.
