Trezor Bridge Guide | Secure Connection for Trezor

This guide explains what Trezor Bridge is, how to set it up safely (or transition to Trezor Suite), and how to troubleshoot common connection issues. Follow the secure steps below to connect your Trezor hardware wallet to your browser or desktop app.

What is Trezor Bridge?

Trezor Bridge was a lightweight connector that allowed Trezor hardware wallets to communicate with browsers and desktop applications. It acted as a local intermediary for USB communication so web apps and the official Trezor software could interact with your device securely.

Important: Trezor now recommends using Trezor Suite and has deprecated the standalone Bridge; see the official guidance below for details. :contentReference[oaicite:0]{index=0}

Current recommendation: use Trezor Suite instead of standalone Trezor Bridge

For the most reliable and secure experience, install and use Trezor Suite (desktop or web) rather than installing standalone Bridge. The Trezor team documents the deprecation of the standalone Bridge and provides instructions for migrating to Trezor Suite. :contentReference[oaicite:1]{index=1}

Quick takeaway: If you already have standalone Bridge installed, expect to uninstall it and move to Trezor Suite for future compatibility. :contentReference[oaicite:2]{index=2}

How to connect your Trezor (recommended workflow)

Download Trezor Suite from the official site (desktop recommended for best compatibility). Verify the download if possible. :contentReference[oaicite:3]{index=3}
Install and open Trezor Suite on your machine.
Plug in your Trezor device via USB and follow the on-screen steps in Trezor Suite to pair the device.
If prompted to allow browser/device access, confirm on the Trezor device screen and in Suite.

Tip: use the desktop Suite when setting up your device for the first time; the Suite bundles everything you need and avoids extra Bridge installs. :contentReference[oaicite:4]{index=4}

If you still need standalone Trezor Bridge (legacy systems)

Some legacy setups or specialized workflows might still reference the standalone Bridge. If you must use it, download only from official Trezor channels and be aware the project is deprecated and may be removed in future releases. :contentReference[oaicite:5]{index=5}

Install (legacy) — general steps

Download the installer from Trezor's official downloads (only). :contentReference[oaicite:6]{index=6}
Run the installer and follow OS prompts.
Restart your browser or computer if the installer asks.

Uninstall standalone Trezor Bridge

If you have standalone Bridge installed and want to remove it (recommended), follow Trezor's uninstall instructions for your OS — macOS and Windows steps are documented by Trezor. :contentReference[oaicite:7]{index=7}

Troubleshooting Trezor Bridge connectivity

Device not detected: Try a different USB cable/port, ensure the device is unlocked, and use the desktop Suite if possible.
Browser blocking access: Close the browser, re-open, and retry; some browsers require explicit permission or do not support legacy Bridge.
Conflicting installations: If you have both standalone Bridge and Suite, uninstall the standalone Bridge to avoid clashes. :contentReference[oaicite:8]{index=8}
Update problems: Use Suite to get the latest firmware and connector updates rather than manual Bridge upgrades.

Security best practices for Trezor Bridge and Suite

Always download Trezor software (Suite or Bridge) only from official Trezor sources or their verified GitHub release pages. :contentReference[oaicite:9]{index=9}
Verify checksums or signatures when available.
Be cautious of phishing sites; type trezor.io manually instead of following search-result links.
Keep your OS, browser, and Trezor Suite up to date.

Security warning: Do not download Bridge or Suite from third-party sites — fake installers are a common attack vector. Confirm the domain and file integrity before installing. :contentReference[oaicite:10]{index=10}
