Steam

Steam maintains a robust security posture through Valve’s proprietary Steam Guard system. This multi-factor authentication (MFA) framework uses mobile-based TOTP codes and QR code sign-ins to prevent unauthorized access, even if account credentials are compromised. Data in transit is protected via industry-standard encryption, and Valve provides granular controls for account recovery, including physical backup codes and SMS-linked restoration. Privacy practices are outlined in a comprehensive policy that details the collection of personal information, such as billing addresses, IP addresses, and hardware configurations, primarily for transaction verification and regional licensing compliance. While Valve shares data with third-party service providers for payment processing and technical support, it strictly prohibits the use of this information for external marketing purposes. Users can manage their digital footprint by adjusting profile visibility settings—ranging from Public to Private—which controls access to game libraries, friend lists, and inventory data. Notably, while the platform provides high security for its core infrastructure, users must remain vigilant against social engineering and third-party malware, as Valve’s automated vetting processes have faced scrutiny regarding malicious community-contributed content.
