Trezor Bridge — Secure, Reliable Communication for Your Trezor

A lightweight background app that lets your Trezor hardware wallet communicate with browsers and desktop apps safely and seamlessly.

What is Trezor Bridge?

Trezor Bridge is the official connector software that establishes a secure channel between your computer and your Trezor hardware wallet (Model One, Model T). It replaces legacy browser plugins and provides cross-platform USB (and in some setups WebUSB) support so web apps and the Trezor Suite desktop app can detect and interact with your device.

Bridge itself does not access your private keys — it simply forwards encrypted messages between the app and the hardware device while keeping sensitive operations fully isolated on the Trezor.

Why you need it

Compatibility: Bridges modern browsers and desktop apps without requiring old plugins.
Stability: Reduces detection issues and improves the reliability of device connections.
Security: Acts only as a message relay — private keys and signing stay on the device.
Cross-platform: Available for Windows, macOS, and Linux.

Install & use — quick steps

1. Download Trezor Bridge from the official Trezor site.
2. Install the correct package for your operating system and follow prompts.
3. Restart your browser if instructed.
4. Plug in your Trezor and open Trezor Suite or a supported web wallet — the app should detect the device automatically.

Tip: On Linux, the Bridge runs as a user service (trezord); use systemctl --user restart trezord to restart it if needed.

Troubleshooting

Common detection problems are usually caused by faulty USB cables, blocked USB ports, browser permissions, or outdated Bridge versions. Try a different cable or port, reinstall Bridge, clear browser cache, or reboot the machine. If your browser supports WebUSB you can also opt to use that instead of Bridge for direct communication.

If you see warnings about unknown software, always verify downloads on the official Trezor domain to avoid fake installers.

Security advice

Trezor Bridge is safe when obtained from the official source. As a best practice, always:

Download Bridge only from trezor.io.
Verify installer checksums when provided.
Keep Trezor device firmware and Bridge updated.
Never share your recovery seed — Bridge does not and must not request it.
