Trezor Bridge — Secure Connection for Your Trezor Hardware Wallet

What is Trezor Bridge?

Trezor Bridge is a lightweight background application designed to create a secure and stable connection between your Trezor device and your computer’s web browser. Without it, your browser might not detect or communicate properly with your hardware wallet. It acts as a trusted bridge, allowing safe communication between your wallet interface and your Trezor without exposing sensitive information to potential online threats.

This software is essential for anyone using a Trezor wallet with desktop browsers that do not support WebUSB or when connecting via older systems that require manual communication channels. It’s developed and maintained by the manufacturer to ensure maximum compatibility and safety.

Why you need Trezor Bridge

Although modern browsers can communicate directly with USB devices through WebUSB, Trezor Bridge remains the most reliable and widely compatible method to connect your Trezor device. It ensures encrypted communication, prevents unauthorized access, and provides a more consistent experience across all major operating systems — including Windows, macOS, and Linux.

Using Trezor Bridge guarantees that your wallet’s communication layer remains isolated from potential browser vulnerabilities. This isolation greatly reduces risks from malicious scripts, extensions, or phishing attempts that may otherwise interfere with wallet operations.

How to install Trezor Bridge

1. Prepare your environment

Before installation, make sure your computer is free from malware and that your browser is up to date. Avoid downloading Trezor Bridge from unofficial sources or third-party websites.

2. Download the installer

Access the official Trezor Bridge download page through the manufacturer’s website. Select the version that corresponds to your operating system (Windows, macOS, or Linux). Save the file to a known location on your device.

3. Install the software

Run the installer and follow the on-screen instructions. On Windows, administrative privileges may be required. On macOS, confirm permissions if prompted. Once installation is complete, the application will run automatically in the background, ready to communicate with your hardware wallet.

4. Verify installation

Connect your Trezor device to your computer using the official USB cable. Open the Trezor interface in your browser. If Trezor Bridge is installed correctly, the interface will automatically detect your device and prompt you to continue setup or access your wallet.

Keeping Trezor Bridge updated

Regular updates ensure compatibility with new firmware releases, browser updates, and operating system changes. The software will usually notify you if an update is available. Always download updates directly from the official Trezor source. Avoid downloading from third-party websites or social media links, as counterfeit versions can compromise your wallet’s security.

After each update, reconnect your device and verify that the connection works as expected. It’s good practice to restart your computer to ensure the new version of Trezor Bridge loads properly.

Security best practices

• Only download Trezor Bridge from the official manufacturer’s site.
• Keep your operating system, browser, and Trezor firmware updated.
• Verify USB cables and avoid using untrusted or modified cables.
• Always confirm actions directly on your Trezor screen before approving any transaction.
• Disconnect your hardware wallet when not in use, especially on shared or public computers.

Trezor Bridge itself does not store or transmit private keys. It only facilitates secure communication between your device and wallet interface. Your private keys always remain stored inside your Trezor hardware wallet.

Troubleshooting common issues

Device not recognized

If your Trezor device isn’t detected, first ensure Trezor Bridge is running in the background. Reconnect the device, try a different USB port or cable, and refresh your browser. Restart your computer if necessary.

Browser compatibility

Some browsers may handle USB permissions differently. If detection fails, try another supported browser or temporarily disable conflicting extensions that might block communication.

Installation problems

If the installer fails to run, ensure you have administrative rights and sufficient storage space. Antivirus software may occasionally flag the installer — temporarily disable it only if you trust the source and re-enable it immediately afterward.

Uninstalling Trezor Bridge

If you need to uninstall Trezor Bridge, go to your system’s application manager and remove it as you would any other program. Restart your computer after removal. You can reinstall it at any time by downloading the latest version from the official source.
