Trezor Bridge Guide | Secure Connection for Trezor Hardware

A clear, step-by-step presentation on installing, troubleshooting and securing Trezor Bridge for desktop access to your hardware wallet.

Overview

This guide explains what Trezor Bridge is, why it’s needed, and how to install, update and troubleshoot it so your Trezor hardware wallet communicates reliably with web apps and Trezor Suite. It’s written for users who want a concise but complete reference with practical steps and official resources.

What is Trezor Bridge?

Trezor Bridge is a small local application that lets your Trezor device securely connect to web-based services and the Trezor Suite by translating USB communication into a secure web interface. Unlike browser extensions, Bridge runs as a background native app and provides stable connectivity across operating systems.

Key benefits

Secure local connection between browser and device.
Cross-platform support: Windows, macOS, Linux.
Automatic handling of USB protocols and device updates.

Before you begin

Make sure you have your Trezor device, its recovery seed backed up, and that you download Bridge only from official Trezor sources (links provided below). Never share your seed or enter it into any website or app.

Install instructions

Download the Bridge installer for your OS.
Run the installer and follow prompts. On macOS you may need to allow the app in System Preferences → Security & Privacy.
Restart your browser after installation.
Plug in your Trezor device and open Trezor Suite or a supported web app.

Updating Bridge

Bridge updates are released periodically. When you see a prompt in Suite or a web app, download the latest Bridge from the official site and run the installer. Regular updates include security patches and improved device compatibility.

Troubleshooting

Common problems & fixes

No device detected: Reconnect the USB cable, try a different port, and ensure Bridge is running. Disable other wallet apps that might capture the device.
Blocked by browser: Restart the browser. For some browsers, Bridge requires a browser restart after install.
Permission issues (macOS): Allow Bridge in Security & Privacy if prompted.
Firewall/antivirus interference: Temporarily allow Bridge through your firewall; do not disable security tools permanently.

Advanced diagnostics

Open Trezor Suite or run command-line tools (when applicable) to check Bridge logs. If the device still fails to connect, collect logs and reach out to official support with details about OS, browser, Bridge version and steps you tried.

Security best practices

Download Bridge only from official Trezor pages. Verify links when in doubt.
Keep your OS and browser updated to reduce attack surface.
Never enter your 12/24-word recovery seed into any software or website.
Use strong local device security (OS account password, full-disk encryption where available).

Closing notes

Trezor Bridge is a small but vital component for a smooth hardware-wallet experience. Follow the install steps, keep software updated, and use official resources if anything unexpected happens. Treat your recovery seed as the ultimate fallback — secure it offline and never disclose it.
