Trezor® Bridge is a lightweight background service that enables secure communication between your Trezor® hardware wallet and web browsers. It acts as a vital link that allows you to access your cryptocurrency assets through the Trezor Suite web interface or other compatible services.
Unlike browser extensions that might pose security risks, Trezor® Bridge runs as a separate application on your computer, providing a more secure connection method. It automatically starts when your system boots and runs in the background, ready to facilitate communication whenever you connect your Trezor® device.
Trezor® Bridge is essential for anyone using a Trezor® hardware wallet with web browsers like Chrome, Firefox, or Edge. It translates the USB communication from your Trezor® device into a format that web applications can understand securely.
While the Trezor Suite app (desktop version) doesn't require Bridge since it communicates directly with your device, the web-based version of Trezor Suite at suite.trezor.io does require Bridge to function properly. This ensures that your Trezor login process remains secure regardless of how you access your wallet.
Note: The desktop version of Trezor Suite (available via Trezor Suite download) doesn't require Bridge as it communicates directly with your device.
There are several ways to install Trezor® Bridge on your computer:
