Trezor Bridge — Download & Install Guide

A friendly, step-by-step overview of what Trezor Bridge does, how to install it safely, and tips to keep your hardware wallet connected — no sign-up required.

What is Trezor Bridge and why it matters

Trezor Bridge is a small helper application that runs on your computer and enables communication between Trezor hardware wallets and web applications (for example, the official Trezor Suite). It acts as a secure, local bridge — translating USB traffic so your browser can interact with the device without exposing private keys to the internet. In short: it lets your Trezor talk to your browser safely and reliably.

Quick essentials

Compatibility: Windows, macOS, Linux

No account needed — local software only

Key features you should know

  • Simple, lightweight background process that starts only when your device is connected.
  • Makes browser-based wallet interfaces possible while keeping keys on the hardware.
  • Automatic updates are available but you control when to install them.
  • Works with USB and certain browser types; avoids exposing devices to network connections.

How to install (general steps)

Installation is straightforward: download the Bridge installer for your operating system and run it. On Windows, you will typically run an .exe and accept the installer prompts. On macOS, mount the .dmg and drag the Bridge into Applications. On Linux, choose the provided .deb/.rpm or use a distribution-specific package. After installation, connect your Trezor device and open your chosen web interface — the browser should automatically detect the bridge.

Step-by-step checklist

  1. Download the correct installer for your OS (use the official Trezor website or verified distribution channels).
  2. Run the installer and grant any required permissions (e.g., allow USB access).
  3. Reconnect your Trezor device and unlock it with your PIN if required.
  4. Open your browser and confirm the device is recognized by the wallet interface.

Troubleshooting & tips

If your device is not recognized, try these quick fixes: reconnect the USB cable, restart the Bridge service from your system tray or services panel, use a different USB port, or temporarily disable browser extensions that affect USB or WebUSB. On Windows, ensure that the driver was installed successfully; on macOS you may need to allow the application in Security & Privacy settings.

Security tips

Always download Bridge from the official Trezor source to avoid tampered installers. Never enter recovery seeds into software or websites — seeds belong only on paper or in your memorized backup scheme. Keep your computer and browser up to date, and avoid installing Bridge on a machine you believe to be compromised.
