Valorant Utilizes TPM for Enhanced Anti-Cheat Measures


Windows 11 has recently introduced the requirement for Trusted Platform Module (TPM) 2.0, causing inconvenience for PC builders using older hardware. However, TPM’s significance extends beyond its application in Windows Hello and Bitlocker, as game developers have started leveraging TPM to bolster their anti-cheating software.

The Role of Valorant and Vanguard

A tweet from the Anti-Cheat Police Department on Twitter sheds light on this development. Users running Windows 11 encountered an error message when launching Valorant, stating that the Vanguard anti-cheat software necessitates TPM version 2.0 and secure boot to be enabled for gameplay.

Expanding Anti-Cheat Measures

Although the exact utilization of TPM and Secure Boot by Riot Games, the developer of Valorant, remains unknown, several Reddit users and Valorant tech support reports confirm their implementation. These measures indicate a new era in combating cheating on Windows 11.

Understanding Anti-Cheat Software

Contrary to popular belief, TPM does not alter the fundamental functioning of anti-cheat software. In essence, anti-cheat software ensures the integrity of the game by verifying the code’s validity, ensuring accurate inputs, and preventing any interference from external programs.

The Role of TPM in Anti-Cheat Measures

A TPM serves as a secure vault for essential data rather than storing actual data. It holds keys and certificates used for authentication and decrypting secured data elsewhere.

Hardware ID (HWID) bans are directly impacted by TPM. HWID bans typically involve blocking the MAC address of the user’s router, but they can also include other identification numbers, such as component combinations or network configurations.

Strengthening HWID Bans with TPM

TPM enables developers to reinforce HWID bans by leveraging its functionality. TPM and Secure Boot verify the initial files loaded on a computer, eliminating any malicious software executed before the operating system loads. Consequently, this ensures that the PC utilizes all necessary components and runs the appropriate software.

Although Riot Games has not provided explicit details regarding how Vanguard anti-cheat utilizes TPM, it is speculated that verifying hardware and enforcing HWID bans are the most feasible applications of TPM and Secure Boot.

Windows 11 Requirement

The TPM 2.0 and Secure Boot requirement exclusively applies to Windows 11. Users lacking these features may continue using Windows 10 until Microsoft ends support in 2025. It remains to be seen if Riot Games will extend the requirement to the older operating system.


Valorant’s implementation of TPM for anti-cheat purposes reflects the ever-evolving landscape of game security. With TPM and Secure Boot, developers can heighten HWID bans, further fortifying their efforts against cheating. As for Windows users, the transition to Windows 11 may necessitate hardware upgrades to meet the TPM requirement. To learn more about OnSpec Electronic, Inc., visit their website here.
