In this article, we’ll walk you through how to enable Secure Boot and fix the TDM 2.0 error that many VALORANT fans encounter when running the game on Windows 11.

Secure Boot and TPM 2.0 are technologies that allow Windows 11 to boot applications with higher trust and security standards. Vanguard, Riot Games’ anti-cheat, requires both of these features to be enabled. If they are disabled, VALORANT won’t launch, and you’ll encounter errors like:

• VAN9001 – This build of Vanguard requires TPM version 2.0 and Secure Boot to be enabled.
• VAN9002 – Initial attestation error: Secure Boot requirement not met.
• VAN9003 – This build of Vanguard requires Secure Boot to be enabled to play.

How to Enable Secure Boot and TPM:

You’ll need to access your system BIOS. Be aware that this process can be complex for those unfamiliar with BIOS settings. Incorrect configuration can harm your system. BIOS menus may vary depending on your motherboard, so proceed with caution.

Steps to enable Secure Boot and TPM:

• Find your BIOS key. It’s usually one of the following: F10, F2, F12, F1, or DEL.
• Shut down your system and turn it back on.
• Press the BIOS key repeatedly until the BIOS menu appears.
• Navigate to the BOOT or Security tab.
• Find and enable Secure Boot.
• Make sure the BIOS mode is set to UEFI.
• Ensure the Secure Boot State is Enabled.
• Locate the TPM setting. It might be named: (“TPM”, “Intel Platform Trust Technology (IPTT)”, “AMD CPU fTPM”, “Trusted Platform Module (TPM)”).Enable TPM 2.0.
• Press F10 to save and exit BIOS.

How to Check if TPM 2.0 is Enabled:

After enabling Secure Boot and TPM 2.0, you can verify that it worked properly:

• Open the Search box near the Windows icon on your taskbar.
• Type tpm.msc and press Enter.
• In the TPM Manufacturing Information section, check the Specification Version.
• If TPM is unsupported or disabled, you’ll see the message: “Compatible TPM cannot be found. A compatible Trusted Platform Module (TPM) cannot be found on this computer…”. This means TPM is either not installed or not enabled in BIOS — refer to the steps above to enable it.

We’ve covered how to enable Secure Boot and TPM 2.0 in Windows 11 to meet Vanguard’s requirements for playing VALORANT. These features not only ensure compatibility with Riot's anti-cheat but also enhance your system’s overall security. Keep in mind that BIOS layouts vary between manufacturers, but they generally follow similar structures — so you should be able to navigate them intuitively.
