Trezor Bridge® — Official Communication

What is Trezor Bridge®?

Trezor Bridge® is a lightweight background application that allows your browser to detect and communicate with Trezor devices. When you connect your Trezor Model One or Trezor Model T to your computer, the Bridge ensures that your web wallet (like Trezor Suite®) can exchange data securely without requiring browser plugins or risky extensions.

Why You Need Trezor Bridge®

Secure Communication: Protects the connection between your Trezor device and wallet interface.
Browser Compatibility: Works seamlessly with Chrome, Firefox, and other modern browsers.
Automatic Detection: No manual setup needed—Bridge detects the device instantly.
Trusted by Trezor Suite®: Essential for connecting the Trezor Suite® desktop and web apps.
Cross-platform Support: Available for Windows, macOS, and Linux operating systems.

How to Download and Install Trezor Bridge®

Follow these steps to set up Trezor Bridge® safely:

Visit the official website: https://trezor.io/bridge.
Select the correct version for your operating system (Windows, macOS, or Linux).
Download and install the setup file. Allow necessary permissions during installation.
Once installed, open Trezor Suite® or your preferred wallet, then connect your Trezor device.
The wallet will automatically recognize the Bridge and establish a secure connection.

How Trezor Bridge® Works

Trezor Bridge® runs quietly in the background as a service, acting as a communication bridge between your device and browser. When you perform actions such as confirming transactions, updating firmware, or managing accounts, the Bridge transmits encrypted messages between your computer and the Trezor hardware securely.

Unlike browser extensions, it minimizes vulnerabilities by using direct USB communication rather than third-party code. This makes Trezor Bridge® a safer and more stable option for crypto asset management.

Troubleshooting and Updates

If your wallet doesn’t recognize your Trezor device, ensure that:

Trezor Bridge® is installed and running.
Your browser allows USB communication.
You’re visiting official Trezor URLs only — trezor.io and suite.trezor.io.

Regular updates to Trezor Bridge® improve compatibility and security. Always download updates from the official site.

Security Reminder

Never share your recovery seed or passphrase with anyone. Trezor Bridge® never asks for private keys—it only facilitates communication. Always verify the authenticity of the website and your device’s firmware before connecting.
