TREZOR BRIDGE — Ultimate Setup & Troubleshooting Guide

Why TREZOR BRIDGE?

TREZOR BRIDGE is the official, lightweight utility that lets your browser or desktop app talk to a Trezor hardware wallet over USB. It creates a secure, local communication channel so you can manage accounts, sign transactions, and update firmware without exposing private keys.

Download & Safety

Always download TREZOR BRIDGE from the official Trezor website. Verify file integrity using checksums when provided. Do not install copies from third-party sources—this protects you from tampered installers and malicious software impersonating the Bridge.

Quick checks:

Visit the official site: trezor.io/bridge
Compare checksums or signatures if available
Use the latest stable release for best compatibility

Installation — Step by step

Installing TREZOR BRIDGE takes just a few minutes. Follow the steps below for your operating system.

Windows

Download the .exe installer.
Run the file and follow prompts. Windows may request permission to install drivers—allow it.
After install, Bridge runs in the background and will be available to supported browsers and apps.

macOS

Download the macOS installer package.
Open the package and follow installation steps. If macOS blocks the installer, open System Settings > Privacy & Security to allow it.
Restart your browser if necessary.

Linux

Choose the package for your distribution: .deb or .rpm.
Install using your package manager and add udev rules if required.
Log out and back in or reboot to apply device permissions.

Web vs Desktop

Desktop versions of Trezor Suite may include native connection methods. TREZOR BRIDGE is primarily for browser-based or third-party wallet connections. Follow the recommended option for your workflow.

Using TREZOR BRIDGE

TREZOR BRIDGE runs automatically after installation. When you connect a Trezor device, supported apps will detect it and prompt you to allow access. Always confirm actions on the device screen before approving.

Open Trezor Suite or a supported web wallet.
Plug your Trezor device into a USB port using a data-capable cable.
Confirm the connection and enter your PIN on the hardware device.

Security & Privacy

TREZOR BRIDGE is a local utility — it does not transmit your seed phrase, private keys, or personal data to external servers. It only forwards messages between your device and the wallet app. Still, follow security best practices:

Never share your seed phrase—Bridge will never ask for it.
Verify download sources and checksums.
Keep device firmware and Bridge up to date.

Troubleshooting — Fast fixes

If your Trezor isn’t connecting, try the following fixes in order. These resolve most issues quickly and safely.

Quick fixes

Switch to a known-good data USB cable (not a charge-only cable).
Try a different USB port, ideally a rear port on desktops.
Restart your browser or the Trezor Suite desktop app.
Reboot your computer if the device remains undetected.

When Bridge isn’t running

Windows/macOS: Look for the Bridge icon in the system tray or menu bar; relaunch if missing.
Linux: Ensure the service is active and udev rules are installed.
Reinstall the latest Bridge installer from the official site.

Permissions & security blocks

Operating systems may block installation or access for security reasons. On macOS, allow the installer in System Settings > Privacy & Security. On Windows, permit driver installation when prompted.

Collecting logs

If you contact support, include: OS and version, Bridge version, Trezor model, browser and version, and a description of steps taken. Logs help support diagnose issues faster.
