How to Check TPM 2.0 in Linux: A Comprehensive Guide


In the world of cybersecurity and data protection, the Trusted Platform Module (TPM) plays a crucial role in ensuring the security of your Linux system. TPM 2.0 is the latest standard, offering enhanced features and improved security. But how do you check if your Linux system is equipped with TPM 2.0? In this comprehensive guide, we will walk you through the steps to check TPM 2.0 in Linux and provide valuable insights into its importance.

How do I check TPM 2.0 in Linux?

Linux users often wonder about the status of TPM 2.0 on their systems. Let’s dive into the steps to check it:

Accessing the Terminal To begin, open your Linux terminal. You can do this by pressing Ctrl + Alt + T or searching for “Terminal” in your applications.

Using the ‘tpm_version’ Command Type the following command into your terminal and press Enter:bashCopy codetpm_version This command will display information about your TPM version, including whether it’s TPM 2.0.

Interpreting the Results The output will provide details about your TPM, including its manufacturer, version, and specifications. Look for the line that specifies “TPM 2.0” to confirm its presence.

Now that you know how to check TPM 2.0 in Linux, let’s explore this topic further.

The Significance of TPM 2.0

TPM 2.0 holds immense significance in the world of cybersecurity. Here’s why it matters:

Enhancing System Security

TPM 2.0 offers advanced security features that help protect your system from various threats. It provides secure storage for encryption keys, making it significantly harder for attackers to access sensitive data.

Secure Boot Process

With TPM 2.0, you can ensure that your Linux system boots securely. It verifies the integrity of the boot process, preventing malware from tampering with critical system components.

Trusted Execution Environments

TPM 2.0 enables the creation of trusted execution environments (TEEs) where critical processes can run securely, shielded from potential attacks.

Enhanced Cryptographic Capabilities

This version of TPM offers improved cryptographic capabilities, allowing for stronger encryption and more robust security protocols.

Checking TPM 2.0 on Different Linux Distributions

While the steps mentioned above are generally applicable, some Linux distributions may have specific commands or utilities for checking TPM 2.0:


On Ubuntu, you can use the ‘tpm_version’ command as described earlier.


For Fedora users, you can also use the ‘tpm_version’ command to check TPM 2.0.


CentOS users can employ the same ‘tpm_version’ command to determine their TPM version.

Arch Linux

On Arch Linux, you can use the ‘tpm_version’ command, which is available through the ‘tpm2-tools’ package.


What if my system doesn’t have TPM 2.0?

If your system doesn’t have TPM 2.0, you can still enhance security by using software-based encryption and other security measures. However, consider upgrading your hardware for optimal security.

Can I enable TPM 2.0 if it’s not already present?

Unfortunately, TPM is a hardware component, and you cannot enable TPM 2.0 if your system lacks it. You would need to purchase hardware that supports TPM 2.0.

Are there any alternatives to TPM for Linux security?

Yes, you can explore alternatives like software-based encryption and secure boot configurations. While they may not provide the same level of security as TPM 2.0, they can still enhance your system’s protection.

Is TPM 2.0 supported on all Linux distributions?

Most modern Linux distributions support TPM 2.0. However, it’s essential to check your specific distribution’s compatibility and ensure that your hardware also supports TPM 2.0.

Can TPM 2.0 prevent all forms of cyberattacks?

While TPM 2.0 enhances security, it cannot guarantee protection against all cyber threats. It is one layer of defense in a comprehensive security strategy.

How often should I check TPM 2.0 on my Linux system?

You should check your TPM 2.0 status whenever you make significant changes to your system, such as hardware upgrades or BIOS updates. Regular checks are also advisable for ongoing security monitoring.

How do I check TPM 2.0 in Linux?

You can check TPM 2.0 status in Linux using the ‘tss2’ or ‘tpm2-tools’ commands.

Is TPM necessary for Linux?

TPM (Trusted Platform Module) is not strictly necessary for Linux, but it can enhance security features like disk encryption and secure boot.

Should I enable TPM 2.0 on Linux?

Enabling TPM 2.0 on Linux depends on your security and encryption requirements; it’s recommended for enhanced security.

Does TPM work on Linux?

Yes, TPM (Trusted Platform Module) is supported and can work on Linux systems for security-related functions.


Ensuring your Linux system is equipped with TPM 2.0 is a vital step in bolstering its security. By following the simple steps outlined in this guide, you can verify the presence of TPM 2.0 on your system and take appropriate measures to enhance your cybersecurity.

In an ever-evolving digital landscape, staying informed and proactive about security is paramount. TPM 2.0 is just one piece of the puzzle, but it’s an essential one that contributes significantly to your system’s overall protection.
