How to Set Up Trezor Bridge

Trezor Bridge is a background application that allows your web browser to communicate securely with your Trezor hardware wallet. It is essential when using the web version of Trezor Suite or connecting your device to third-party browser-based wallets.

Step 1: Prepare Your Computer

Before installing Trezor Bridge, ensure:

  • Your internet connection is secure.
  • You’re using a supported operating system (Windows, macOS, Linux).
  • Your Trezor device is not connected yet.

This helps prevent unnecessary connection issues during installation.

Step 2: Visit the Official Trezor Website

Go to the official setup page:

This ensures you're downloading the software from a trusted source.

Step 3: Choose Your Trezor Device

Select your Trezor model (Trezor Model One or Trezor Model T).
You’ll be guided to set up your device, and the page will automatically prompt you to download Trezor Bridge if you're using a browser (rather than the Trezor Suite desktop app).

Step 4: Download Trezor Bridge

Click the download link for Trezor Bridge compatible with your operating system:

  • Windows: .exe file
  • macOS: .pkg file
  • Linux: .tar.gz or via package manager

After downloading, locate the installer file on your computer.

Step 5: Install Trezor Bridge

On Windows:

  1. Run the .exe installer.
  2. Follow the setup instructions.
  3. Allow permissions if prompted by the system.
  4. Complete installation and restart your browser.

On macOS:

  1. Double-click the .pkg file.
  2. Follow the on-screen steps to install.
  3. After installation, restart your browser.

On Linux:

  1. Follow the instructions provided on the Trezor website.
  2. You may use command-line tools to install depending on your distribution.
  3. Restart your browser once installation is done.

Step 6: Verify Bridge Is Running

After installing and restarting your browser:

  • Open a new browser window.
  • Visit https://suite.trezor.io/web/ or return to trezor.io/start.
  • Plug in your Trezor device.
  • The browser should now detect your Trezor automatically.

If the device is recognized and you are not prompted to install Bridge again, everything is working correctly.

Step 7: Keep Trezor Bridge Updated

Trezor Bridge usually updates itself silently in the background. To ensure it's always working properly:

  • Occasionally restart your browser or computer.
  • Reinstall the latest version from trezor.io/start if connection issues arise.

Troubleshooting Tips

  • Trezor not recognized in browser?
    Ensure Trezor Bridge is installed and your browser is up to date. Also, try a different USB port.
  • Using browser extensions like MetaMask?
    Disable or manage them if they conflict with Trezor communication.
  • On macOS Monterey or later?
    You may need to allow permissions for Bridge under System Preferences > Security & Privacy.

Do You Need Trezor Bridge?

You only need Trezor Bridge if:

  • You are using the web version of Trezor Suite
  • You want to access your wallet from a browser
  • You’re integrating Trezor with third-party browser apps

If you’re using the Trezor Suite desktop app, Bridge is not required.

Conclusion

Setting up Trezor Bridge is a fast and essential step for using your Trezor device in the browser. Once installed, it runs quietly in the background and ensures secure communication between your hardware wallet and the web interface—without compromising the safety of your private keys.
