Frequently Asked Questions

What is TPM 2.0 and why does Vanguard need it?
TPM 2.0 is a security chip that provides hardware-level protection against cheating and tampering. Riot Vanguard requires it to verify system integrity and prevent unauthorized modifications to game files.
Will enabling TPM 2.0 affect other programs or games?
Enabling TPM 2.0 generally doesn't affect other programs negatively. Some security software and enterprise applications may actually benefit from TPM being enabled. However, very old software might have compatibility issues.
My computer doesn't have TPM 2.0 support, can I still play Valorant?
Unfortunately, TPM 2.0 is a hard requirement for Valorant and other Riot games using Vanguard. Computers without TPM 2.0 support cannot run these games. You would need to upgrade to newer hardware that includes TPM 2.0.
I enabled TPM but still get VAN 9003 error, what should I do?
Try updating your BIOS to the latest version, ensure Secure Boot is also enabled, clear the TPM in BIOS settings and re-enable it, or check if your TPM is set to 'Discrete' mode instead of 'Firmware' mode in BIOS.
Can I bypass the TPM requirement for Vanguard?
No, there is no legitimate way to bypass TPM 2.0 requirement for Vanguard. Any methods claiming to bypass this requirement are likely malware or will result in account bans. TPM 2.0 is a core security requirement that cannot be disabled.
