What is Trezor® Bridge?

Trezor Bridge is a background communication service that enables your Trezor® hardware wallet to connect with supported web browsers. It acts as a secure bridge between your device and browser-based interfaces like the Trezor Wallet web interface, allowing for seamless interaction while maintaining the highest security standards.

Unlike the standalone Trezor Suite application, which includes its own communication drivers, web browser access requires Bridge to facilitate the connection between your computer's USB ports and the browser environment. This is essential for the Trezor Bridge login process that establishes a secure channel for your device to communicate with web interfaces.

Key Functions of Trezor® Bridge

Secure Communication Channel

Trezor Bridge creates an encrypted communication pathway between your Trezor® device and supported web browsers (Chrome, Firefox, and Brave). This ensures that all data transmitted remains confidential and protected from interception.

Browser Compatibility

By installing Bridge, you enable web browsers to recognize and communicate with your Trezor® device, which they cannot do natively due to browser security restrictions around USB device access.

Background Operation

Once installed, Bridge runs as a background service that automatically starts when needed. It doesn't require manual activation each time you want to access your Trezor Wallet through a browser.

Cross-Platform Support

Trezor Bridge is available for Windows, macOS, and Linux operating systems, ensuring broad compatibility regardless of your computer setup.

Installation and Setup Process

1 Initial Setup: After unboxing your Trezor® device, visit trezor.io/start for the initial configuration process.

2 Automatic Detection: When you first connect your Trezor® to a web browser interface, it will automatically detect if Bridge needs to be installed and provide download instructions.

3 Download and Install: Follow the prompts to download and install Trezor Bridge for your operating system. The installation process is straightforward and typically completes within minutes.

4 Restart Browser: After installation, restart your web browser to ensure it recognizes the newly installed Bridge service.

5 Connection Established: Once Bridge is installed, you can complete the Trezor login process through your web browser, with Bridge facilitating the secure communication.

Note: If you primarily use the desktop Trezor Suite application (available through Trezor Suite download), you don't need Bridge as Suite includes its own communication drivers.

Troubleshooting Common Bridge Issues

While Trezor Bridge is designed to work seamlessly, occasionally users may encounter connection issues:

Frequently Asked Questions

Do I need Trezor Bridge if I use Trezor Suite?
No, the desktop version of Trezor Suite includes its own communication drivers. Bridge is only necessary if you want to access your wallet through a web browser instead of the Suite application.
Is Trezor Bridge compatible with all operating systems?
Yes, Trezor Bridge is available for Windows, macOS, and Linux. The installation process varies slightly between operating systems but functionality remains consistent.
How do I know if Trezor Bridge is running correctly?
Bridge runs as a background service. If your Trezor® device is recognized when connected to a supported web browser, Bridge is functioning properly. You can also check your system's background processes to see if it's active.
Does Trezor Bridge pose any security risk?
No, Bridge is developed and maintained by SatoshiLabs, the creators of Trezor®. It doesn't have access to your private keys or recovery seed, which always remain secure on your hardware device.
Can I use the Trezor Suite app on mobile with Bridge?
The Trezor Suite app for mobile devices doesn't require Bridge, as mobile operating systems handle USB connections differently. Bridge is specifically designed for desktop browser communication.
What should I do if Bridge stops working after a browser update?
Browser updates occasionally affect connectivity. Usually, simply restarting your browser or reinstalling Bridge resolves these issues. The Trezor website always provides the most current version compatible with latest browsers.
