Trying to connect your Trezor hardware wallet to the Trezor Suite app but running into issues?
You likely need to install Trezor Bridge.

Trezor Bridge is a small, secure background application that enables your Trezor hardware wallet to communicate with the Trezor Suite web interface on your computer.

This guide explains what Trezor Bridge is, how to install it safely, and how to fix “Trezor Bridge not working” issues — step-by-step and with official security best practices.

Trezor Bridge acts as the communication link between your Trezor device and your web browser. It’s what allows your computer to talk to your hardware wallet when you use the Trezor Suite Web App.

Think of it like a printer driver — without it, your computer can’t “speak” to your printer. Similarly, without the Bridge, your browser can’t recognize your Trezor device.

💡 Note: If you use the Trezor Suite desktop app, you don’t need Trezor Bridge. The desktop version includes built-in communication support.

Trezor Bridge is developed by SatoshiLabs, the creators of Trezor, and is open-source for transparency and security.

Follow these steps carefully to install Trezor Bridge safely and correctly:

1. Go to the official website:
   Visit trezor.io/start.

2. Connect your Trezor device:
   Plug in your Trezor Model One or Trezor Model T using a trusted USB cable.

3. Select your model:
   The website automatically detects your model and operating system.

4. Download Trezor Bridge:
   Click “Install Trezor Bridge”. Your OS (Windows, macOS, or Linux) will determine the correct file.

5. Run the installer:
   Open the downloaded file and follow the setup wizard instructions.

6. Restart your browser:
   After installation, restart Chrome, Firefox, or Edge.

7. Reconnect your device:
   Visit Trezor Suite Web App and connect your wallet. It should now be detected.

Even when installed properly, some users encounter “Trezor Bridge not working” messages. Below are the most common problems and their solutions.

1. “Trezor Bridge Not Working” or “Cannot Connect to Bridge”

Fix:

• Restart your browser and computer.

• Confirm that the Trezor Bridge process is running in your system tray.

• Check for other USB communication programs causing conflicts.

2. “Trezor Bridge Is Not Detected”

Fix:

• Try a different USB cable (ideally the original one).

• Plug directly into your computer (avoid USB hubs).

• Uninstall and reinstall Trezor Bridge from trezor.io/start.

3. Firewall or Antivirus Blocking Trezor Bridge

Fix:

• Open your antivirus or firewall settings.

• Add Trezor Bridge as an exception or trusted app.

• On Windows: Go to “Allowed Apps” → “Change Settings” → Add Trezor Bridge.

4. Consider Using Trezor Suite Desktop Instead

If your web setup keeps failing, switch to the Trezor Suite desktop app — a more reliable solution that doesn’t require Bridge.
Download it securely from trezor.io/start.

Trezor Bridge may be lightweight, but it plays a crucial role in ensuring secure communication between your browser and your hardware wallet.

Remember these key points:

• Always download Trezor Bridge from trezor.io/start

• Never install Bridge from any other source.

• Keep your Trezor firmware and Bridge updated for maximum compatibility and security.

• If connection issues persist, try using the Trezor Suite desktop app instead.
