Trezor Bridge – Secure Connection Between Device and Desktop

Introduction

Trezor Bridge is the official, lightweight service that enables secure communication between your Trezor hardware wallet and desktop applications such as Trezor Suite. It replaces older browser plugins and simplifies device detection on Windows, macOS, and Linux.

What Trezor Bridge Does

• Creates an encrypted channel between the Trezor device and desktop apps.
• Automatically detects connected Trezor devices when Trezor Suite or compatible apps are opened.
• Removes the need for browser extensions, running as a trusted background service instead.

How to Install

Visit the official Trezor start page (trezor.io/start) or the Bridge download page, choose your operating system, download the installer, and run it. After installation the Bridge runs in the background and provides seamless device access whenever you connect your Trezor.

Security and Privacy

Trezor Bridge does not store wallet data or private keys. It only forwards encrypted messages between the desktop app and the hardware device. All signing operations happen on the Trezor device itself, preserving hardware-level security and ensuring private keys never leave the device.

Troubleshooting

• Ensure Bridge is installed from the official Trezor site to avoid tampered downloads.
• Restart the Bridge (or your computer) if your device is not detected.
• Check USB connection and try a different cable or port if detection fails.

Conclusion

Trezor Bridge is a small but critical component for desktop Trezor workflows. By running a secure, dedicated bridge service you get reliable device detection and encrypted communication while keeping private keys isolated on the hardware wallet.
