Trezor Bridge

Install, connect, and troubleshoot the Trezor Bridge to securely use your Trezor hardware wallet.

What is Trezor Bridge?

Trezor Bridge is a small local application that enables secure communication between your Trezor hardware wallet and web-based interfaces (like Trezor Suite or compatible third-party wallets). It ensures reliable USB connectivity across browsers and operating systems.

Get Started

Estimated install: 2–5 minutes

Install Trezor Bridge

Install Trezor Bridge

Always download Trezor Bridge from official sources. Do not trust links from emails or social media. The official Trezor website and Trezor Suite will guide you to the correct installer for Windows, macOS, and Linux.

Quick installation steps

  1. Download: Visit the official Trezor download page (trezor.io) and choose Trezor Bridge for your OS.
  2. Run installer: Open the downloaded installer and follow on-screen instructions. On macOS, you may need to allow the installation in System Preferences > Security.
  3. Restart browser: After installation, restart your browser to ensure it detects the Bridge service.
  4. Open Trezor Suite: Launch Trezor Suite or connect via the recommended web interface and follow prompts to pair your device.
  5. Grant permissions: Approve USB access when your browser requests it — your Trezor device will display a confirmation as well.

Notes

Trezor Bridge runs locally and does not transmit your private keys. It simply facilitates USB communication between browser and device. For advanced setups use Trezor Suite's desktop app which bundles necessary components.

Connect Your Trezor Device

Use the official USB cable shipped with your device. Connect the device, unlock with your PIN, and confirm pairing on-device. Always verify any address shown during transactions on the physical Trezor screen — not on your computer.

Pairing checklist

  • Device firmware up to date.
  • Use a direct USB port (avoid hubs when possible).
  • Allow browser permissions for USB when prompted.
  • Confirm device prompts directly on the Trezor screen.

Security Best Practices

Your Trezor secures private keys — treat your recovery seed and PIN as the highest-priority secrets. Never enter your seed into a website or share it. Always verify URLs and use official software.

Pro tip: Use the official Trezor Suite desktop app for maximum reliability and to avoid browser-related permission issues.

Troubleshooting Common Issues

If Trezor Bridge is not detected or your browser cannot connect, try these steps:

  1. Ensure Bridge is installed and the Bridge service is running (check system tray / activity monitor).
  2. Restart the browser or try a different browser (Chrome/Edge/Firefox recommended).
  3. Try a different USB port or cable; avoid unpowered USB hubs.
  4. Reboot your computer and reconnect the device.
  5. Update device firmware in Trezor Suite if available.
  6. On macOS, go to System Preferences → Security & Privacy and allow the installer if blocked.

When to contact support

If the device remains unrecognized after these steps, contact official Trezor support with logs and system information — but never share your recovery seed or PIN.
