What is Trezor Bridge?
Trezor Bridge is a small background service that allows your Trezor hardware wallet to communicate securely with your computer’s browser. It acts as a connector between your Trezor device and web-based wallet interfaces such as Trezor Suite Web.
When installed, it ensures a smooth and stable connection to your wallet without requiring browser extensions. This makes it compatible across modern browsers and operating systems.
Why Use Trezor Bridge?
Trezor Bridge offers a secure and extension-free method for connecting your hardware wallet. Unlike browser extensions, Bridge works directly with your system, avoiding compatibility issues and ensuring full privacy.
- Works seamlessly with Trezor Suite Web
- No browser extension required
- More stable than WebUSB connections
- Supports Chrome, Firefox, Edge, and other major browsers
- Available for Windows, macOS, and Linux
How to Install Trezor Bridge
Setting up Trezor Bridge is simple and takes only a few minutes. Follow these steps:
- Go to the official Trezor Bridge download page: https://trezor.io/bridge
- Select your operating system (Windows, macOS, or Linux)
- Download the installer and run it
- Follow the on-screen instructions to complete installation

After installation, Trezor Bridge will run in the background automatically when needed. There is no need to launch it manually.
Connecting Your Trezor Device
Once Trezor Bridge is installed, you can connect your Trezor hardware wallet to Trezor Suite Web. Here's how:
- Connect your Trezor device to your computer using a USB cable
- Open your browser and go to suite.trezor.io/web
- Follow the prompts in the browser to detect and authorize your device
- Approve any actions using your Trezor’s screen for verification
If you are prompted to allow communication, be sure to confirm all requests from your browser and Bridge service.
Troubleshooting Common Issues
If Trezor Suite Web does not recognize your device or Bridge does not work as expected, try the following:
- Ensure Bridge is installed and running in the background
- Restart your browser
- Try a different USB port or cable
- Disable any conflicting browser extensions or wallet apps
- Reinstall Bridge if problems persist
Security and Privacy
Trezor Bridge is developed by SatoshiLabs, the makers of Trezor, and is open-source. It does not collect or share personal data. All communications between your wallet and your browser happen locally and securely.
Trezor Bridge does not access your recovery phrase, private keys, or PIN code. These remain stored securely on your Trezor device and never leave the hardware.
When to Use Trezor Bridge
Trezor Bridge is required when using the web version of Trezor Suite. If you are using the desktop version of Trezor Suite, Bridge is not necessary.
You may also need Bridge if you're interacting with third-party wallets or services that require secure USB-based communication with your Trezor.
Uninstalling or Updating Trezor Bridge
To uninstall Trezor Bridge, go to your operating system’s application manager and remove it like any other program. To update Bridge, visit the official download page and install the latest version—it will overwrite the old one automatically.
