Some PC players may discover that a system capable of running demanding games still cannot access Modern Warfare 4's online modes. One possible reason is the game's security requirements. Modern Warfare 4 requires TPM 2.0 and Secure Boot for online play on PC. These features help establish a more trustworthy system environment and support Call of Duty's anti-cheat security measures.
What Is TPM 2.0?
TPM stands for Trusted Platform Module. It is a security component that can support hardware-based cryptographic operations and help establish information about a computer's trusted state. On supported AMD systems, TPM functionality may be provided through firmware, commonly called AMD CPU fTPM. Supported Intel systems may use Intel Platform Trust Technology, also known as Intel PTT. The exact configuration depends on your motherboard, processor, firmware, and operating system.
What Is Secure Boot?
Secure Boot is a UEFI firmware feature designed to help ensure that trusted software is loaded during the startup process. A PC may support Secure Boot without having it enabled. The boot mode and disk configuration can also affect whether the setting is available.
How to Check Your Settings
To check TPM status in Windows:
1. Press Windows + R.
2. Enter tpm.msc.
3. Press Enter and examine the TPM status and specification version.
To check Secure Boot status:
1. Press Windows + R.
2. Enter msinfo32.
3. Press Enter.
4. Look for the BIOS Mode and Secure Boot State fields.
These checks can help identify whether the required features are available and enabled.
Be Careful With BIOS Changes
Changing firmware settings without understanding your current configuration can create startup problems. Consult your motherboard or PC manufacturer's documentation before making changes, especially if Windows uses a legacy boot configuration. For exact requirements and supported configurations, consult the official Activision TPM 2.0 and Secure Boot guide.
Final Thoughts
TPM 2.0 and Secure Boot are compatibility requirements, not proof that a player has been banned. Diagnose the actual message and system configuration before assuming an account-enforcement problem.
