Secure Connection for Trezor Devices

Make your browser and desktop apps talk to your Trezor—safely.

Trezor Bridge is a small background service that allows your computer to communicate with your Trezor hardware wallet. It ensures reliable device detection and secure message passing so that confirmations always stay on your hardware screen—not on random websites.

What is Trezor Bridge?

Bridge is the secure connector between your Trezor device and software such as Trezor Suite (desktop or web). It runs locally and handles communication with the device, so your keys remain offline inside the hardware wallet while Suite provides a user‑friendly interface.

Local & lightweight: Installs in minutes and runs quietly in the background.
Consistent detection: Helps browsers and apps recognize the device across operating systems.
Security‑first design: Sensitive actions still require on‑device confirmation; Bridge never exposes seed or private keys.

Download Trezor Bridge

Always download from the official site. Type the URL manually and never trust third‑party mirrors. After installation, Bridge runs automatically when needed.

Install & verify in six steps

  1. 1) Go to the official page: Type trezor.io/start or use the prompt in Trezor Suite.
  2. 2) Download the installer: Choose the package for your operating system and save it locally.
  3. 3) Run the installer: Follow on‑screen instructions. Admin permission may be required.
  4. 4) Reopen Suite or your browser: Bridge will start in the background automatically.
  5. 5) Connect your device: Plug in your Trezor and unlock it with your PIN (and optional passphrase).
  6. 6) Test detection: Add or open an account in Suite and verify that addresses appear only after confirmation on the hardware screen.

Troubleshooting: quick fixes

Bridge not detected? Reinstall via the official prompt, then unplug/replug your device and restart Suite.
Browser conflicts? Use a clean profile, disable suspicious extensions, or switch to Desktop Suite.
Permissions blocked? On macOS/Linux, allow the service/daemon if prompted. On Windows, confirm driver permissions.
Address mismatch? Stop. Only trust addresses that match on the hardware display.

FAQ

Is Trezor Bridge required for everyone?

Not always. Desktop Suite can talk to devices directly on many systems. The official flow will tell you if Bridge is recommended for your setup.

Does Bridge ever see my recovery seed?

No. The seed and private keys never leave the hardware wallet. Bridge only facilitates communication; confirmations happen on the device screen.

How do I know I installed the genuine software?

Download from the official domain, verify signatures where available, and avoid third‑party mirrors. If the installer behaves oddly, stop and re‑check the source.

Can I uninstall Bridge later?

Yes. If your environment no longer needs it, you can uninstall from your OS settings. Suite will prompt again if it becomes necessary.
