Trezor Bridge is a crucial communication tool that enables secure interaction between your Trezor® hardware wallet and web browsers. This background service acts as a secure bridge, allowing your browser to communicate with your Trezor Wallet without compromising security or requiring additional browser extensions.
Unlike traditional software that runs directly in the browser, Trezor Bridge operates as a standalone service on your computer. This architecture provides enhanced security by creating a controlled communication channel that prevents malicious websites from directly accessing your hardware device.
Get Trezor Bridge via trezor.io/start →Creates an encrypted channel between your browser and Trezor® device, ensuring all data transmission remains protected from interception
Seamlessly integrates with popular browsers like Chrome, Firefox, and Edge without requiring additional extensions or plugins
Runs as a background service, automatically starting when needed and remaining available for Trezor Bridge login requests
Note: The Trezor Bridge login process happens automatically when you connect your device. You don't need to manually log into Bridge itself.
During the Trezor Suite download and installation process, Trezor Bridge is automatically installed as a required component. This is the recommended method for most users.
If needed, you can download Bridge separately from the official Trezor® website. Visit trezor.io/start and look for the Bridge download option.
After installation, Bridge runs as a background service. You can verify it's working by connecting your Trezor® device and attempting a Trezor login through a web browser.
If Bridge isn't detected, try restarting the service or reinstalling. The service should start automatically with your operating system.
