Streamline connectivity and protect your assets with Trezor.io/start
Trezor Bridge is an essential piece of software that connects your Trezor Hardware Wallet to your browser. It enables secure, local communication between your device and your web-based wallet interfaces like Trezor.io/start.
Bridge is especially useful when WebUSB is unsupported or restricted, such as on Firefox or older versions of operating systems. Without Trezor Bridge, your wallet might not be detected or may struggle to complete secure authentication like Trezor Login.
Crypto security depends on isolated, verifiable actions. Trezor Bridge ensures that no third-party applications can interfere with or spoof communication between your browser and your hardware wallet.
If you're accessing Trezor Suite through the web, or your browser doesn't support direct USB communication, you should install Trezor Bridge from the official Trezor.io/start website.
Bridge works best with Firefox, Safari, and other non-Chromium browsers, or when system policies block WebUSB.
Follow this process to install the Bridge software safely:
Go to Trezor.io/start. The page will detect your OS and suggest the appropriate Bridge installer.
Download the file and follow the on-screen instructions. On macOS, allow the installer in your Security & Privacy settings.
Once installed, restart your browser to activate the service. You’ll notice your Trezor device is now fully recognized on Trezor.io/start.
If you use the Trezor Suite desktop app, Bridge is optional. Suite manages device communication internally, removing the need for browser-level support.
Login to dApps or exchanges using your hardware wallet with Trezor Login — without typing passwords.
Bridge maintains a local connection, ensuring lightning-fast interaction without relying on cloud APIs.
No data is sent externally. All communication remains on your machine, making Bridge a privacy-respecting tool.
Unlike WebUSB, Bridge can run in the background and automatically starts when your PC boots.
