⚠️ Important Note

Trezor Bridge is being phased out in favor of Trezor Suite. For most users, we recommend using Trezor Suite which includes built-in device communication. Bridge is primarily needed for legacy web wallet access and third-party applications.

What is Trezor Bridge?

Trezor Bridge is a background service that enables secure communication between your Trezor hardware wallet and web browsers. It acts as a bridge between the web-based Trezor Wallet and your physical device.

  • Secure Communication - Encrypted connection between browser and device
  • Background Service - Runs automatically when needed
  • Cross-Browser Support - Works with Chrome, Firefox, Edge, and Safari
  • Low Resource Usage - Minimal system impact
  • Automatic Updates - Keeps itself updated for security

Frequently Asked Questions

Do I still need Bridge if I use Trezor Suite? +
No, Trezor Suite includes built-in device communication and does not require Bridge. Bridge is primarily needed for the web-based Trezor Wallet (wallet.trezor.io) and third-party web applications that haven't migrated to the new Trezor Connect library.
Is Bridge being discontinued? +
Yes, Bridge is being phased out in favor of modern solutions. Trezor Suite is the recommended application for most users, and new web applications should use Trezor Connect library which doesn't require Bridge. However, Bridge will continue to be maintained for legacy support.
Why do I need administrator privileges to install Bridge? +
Bridge installs as a system service that needs to run in the background and communicate with USB devices. This requires elevated privileges to set up proper system integration and USB access rules. The application itself runs with standard user privileges after installation.
Can I use Bridge with multiple browsers? +
Yes, Bridge works with all supported browsers simultaneously. Once installed, it will automatically handle communication requests from Chrome, Firefox, Edge, Safari, and other compatible browsers without needing separate installations or configuration.
How do I know if Bridge is running? +
On Windows, check the system tray for the Trezor Bridge icon. On macOS, look in the menu bar. On Linux, check if the service is running with systemctl --user status trezor-bridge. The service starts automatically when needed and runs in the background.
What's the difference between Bridge and Trezor Suite? +
Bridge is a lightweight communication tool that enables web browsers to talk to Trezor devices. Trezor Suite is a full-featured desktop application that includes device communication, portfolio management, exchange features, and more. Suite doesn't require Bridge as it has built-in communication capabilities.
