How to Set Up Trezor Bridge


Trezor Bridge is background software that enables secure, direct communication between your Trezor device and your web browser. It's required when you're using Trezor via the browser interface (like suite.trezor.io/web) rather than the desktop app.

🔧 What You’ll Need

  • A Trezor Model One or Trezor Model T
  • A Windows, macOS, or Linux computer
  • A supported browser (Chrome, Firefox, or Edge)
  • An internet connection
  • A USB cable for your device

📝 Step-by-Step Installation

Step 1: Go to the Official Trezor Bridge Page

Visit the official Bridge download page:
 https://trezor.io/bridge

Step 2: Download the Correct Version

Click the download button that matches your operating system:

  • Windows
  • macOS
  • Linux

Step 3: Install Trezor Bridge

  • Open the downloaded file.
  • Follow the installation prompts.
  • Grant permissions if your operating system asks for approval.

Once installed, Trezor Bridge will run silently in the background.

✅ Step 4: Restart Your Computer (Recommended)

This step ensures Trezor Bridge is fully loaded and any previous USB issues are cleared.

🔌 Step 5: Connect Your Trezor Device

  • Plug your Trezor device into your computer using the original USB cable.
  • Use a direct USB port (not a hub or extension).
  • Unlock the device if prompted.

🌐 Step 6: Visit suite.trezor.io/web

  • Open your browser and go to suite.trezor.io/web.
  • The site will now detect Trezor Bridge and begin interacting with your device.
  • You may need to approve a connection prompt from your browser.

🧠 Tips for a Smooth Setup

  • Use official downloads only from trezor.io
  • Avoid USB hubs — connect your Trezor directly
  • Use a quality USB cable — charge-only cables won’t work
  • Keep your browser updated to the latest version
  • Disable interfering extensions (like ad blockers or antivirus browser plugins) during setup

🛠️ How to Verify Trezor Bridge Is Running

  • Windows: Look in the system tray (bottom-right corner) for a Trezor-related background process.
  • macOS/Linux: Use Activity Monitor or System Monitor to confirm that a process like trezord or trezor-bridge is active.

When You Don’t Need Trezor Bridge

If you're using the Trezor Suite desktop app, you do not need to install Trezor Bridge. The desktop version handles communication without it.

Final Thoughts
