Trezor Bridge Download — How to Install, Update & Use

A clear, step-by-step guide to safely download, install, and maintain Trezor Bridge, the official connector between your Trezor device and desktop browser or Trezor Suite.

What is Trezor Bridge?

Trezor Bridge is a small, official application that enables secure communication between your Trezor hardware wallet and your web browser or desktop environment. It ensures your device is recognized, handles USB communication safely, and allows Trezor Suite or browser-based apps to sign transactions while keeping keys on the device.

Why you need Trezor Bridge Download

Modern browsers and operating systems limit direct USB access for security reasons. Installing Trezor Bridge provides a trusted bridge layer so your computer can securely detect and interact with your Trezor device. Without it, web-based wallet interfaces may not detect the device or may require older extensions.

1. How to get the Trezor Bridge Download (official)

Follow these official steps to download Trezor Bridge safely:

  1. Open your browser and go to https://trezor.io/bridge.
  2. Choose the correct installer for your operating system (Windows, macOS, or Linux).
  3. Download the file and verify the source — avoid third-party mirrors.
  4. Run the installer and follow the on-screen prompts to complete installation.

Tip: Always download directly from the official domain to avoid counterfeit or tampered installers.

2. Installing Trezor Bridge (step-by-step)

Quick installation guide:

  • Windows: Run the .exe installer and allow the application to run. Grant permissions if prompted.
  • macOS: Open the .dmg file, drag the Trezor Bridge app to Applications, then launch it.
  • Linux: Follow the distribution-specific package instructions or use the provided AppImage where available.

After installation, the Bridge runs in the background and your browser should detect the Trezor device when connected via USB.

3. Updating Trezor Bridge

Keep Bridge updated to ensure compatibility and security:

  • Check for updates on trezor.io/bridge or within Trezor Suite prompts.
  • Download the latest installer and re-run it; Bridge typically replaces the older version.
  • Restart your browser after updating to ensure the new Bridge is loaded.

4. Troubleshooting Trezor Bridge Download & Connection Issues

If your device is not detected or Bridge appears not to work, try these steps:

  • Confirm Bridge is installed and the service/process is running (check system tray or background processes).
  • Use an original or known-good USB cable; avoid USB hubs that can interrupt communication.
  • Restart your computer and reconnect the Trezor device.
  • Ensure your browser is up to date; try a different browser if detection fails.
  • Temporarily disable browser extensions that may block USB communication.

If issues persist, consult Trezor Support for detailed diagnostics: support.trezor.io.

5. Security Considerations

Trezor Bridge itself does not store private keys or personal data. It simply forwards USB communication between your Trezor device and local applications. Still, keep these practices in mind:

  • Download Bridge only from trezor.io/bridge.
  • Verify installer integrity where checksums or signatures are provided.
  • Keep your operating system and browser patched and updated.
  • Use Trezor Suite or trusted wallet interfaces that explicitly support Trezor devices.

6. Compatibility & Alternatives

Trezor Bridge supports Windows, macOS, and Linux. For some setups, alternative connection options exist:

  • Trezor Suite: The official desktop/web app integrates with Bridge for a smooth experience.
  • Browser-based interfaces: Some third-party dApps work with Bridge-enabled connections.
  • Legacy extensions: Older browser extensions may be deprecated — Bridge replaces the need for them.
