Trezor Bridge® Official Setup & Guide

Learn how to install, configure, and troubleshoot Trezor Bridge—the essential software that enables your Trezor hardware wallet to communicate with your computer and web browsers securely.

What is Trezor Bridge?

Trezor Bridge is a lightweight background application that allows your Trezor device to interact with supported browsers and wallets. Without Bridge, your hardware wallet cannot properly send or receive commands from web interfaces.

Unlike browser plugins, Trezor Bridge is installed at the system level, making the communication more stable and secure. It runs silently in the background while ensuring your private keys never leave the device.

Step 1: Download Trezor Bridge

Download the latest version of Trezor Bridge directly from the official Trezor website.

  • Windows – Supports Windows 10 and above.
  • macOS – Supports macOS 10.13 and later.
  • Linux – Compatible with most modern distributions.

Always verify you are on the official Trezor site before downloading.

Step 2: Install Trezor Bridge

Windows

Run the installer, accept permissions, and reboot if prompted.

macOS

Open the DMG, drag Trezor Bridge to Applications, approve system dialog if shown.

Linux

Use the provided .deb or .rpm package. Ensure udev rules are configured.

Step 3: Connect with Trezor Suite

Once Bridge is installed, open Trezor Suite. Plug in your Trezor device and follow the guided steps to initialize or restore a wallet.

  • Initialize as new device or recover from seed phrase.
  • Set a strong PIN.
  • Backup your recovery seed securely.

Advanced Security Practices

  • Never share your recovery phrase with anyone.
  • Store backups in multiple secure locations.
  • Keep Trezor Bridge and Trezor Suite updated.
  • Verify URLs—phishing sites often imitate the official interface.

Troubleshooting Trezor Bridge

If your device isn’t detected:

  • Check your USB cable and port.
  • Restart Trezor Bridge service.
  • Ensure your browser supports WebUSB or Bridge communication.
  • On Linux, confirm udev rules are installed correctly.

Frequently Asked Questions

Do I need Trezor Bridge for all browsers?

Bridge is required for Firefox, Safari, and other browsers that do not support WebUSB. For Chrome and Chromium-based browsers, WebUSB can sometimes work without Bridge, but installing Bridge is still recommended.

Is Trezor Bridge safe?

Yes. It is open source and officially maintained by Trezor. It never exposes your private keys to your computer.

Conclusion

Trezor Bridge is the silent, essential link that connects your Trezor hardware wallet to the digital world. With proper installation and safe practices, you can transact confidently knowing that your keys remain secure inside your hardware wallet.
