Trezor Wallet

What is Trezor® Bridge?

Trezor Bridge is a background program that allows your Trezor® hardware wallet to communicate directly with supported web browsers. It works as a link between your device and browser-based wallets like Trezor Wallet, ensuring smooth operations without compromising security.

Unlike the all-in-one Trezor Suite desktop app that includes built-in drivers, browsers need Bridge to manage communication with USB-connected devices. This service plays a vital role in enabling Trezor Bridge login and ensures secure data transfer between your device and online wallet interface.

Main Features of Trezor® Bridge

Encrypted Communication

Bridge establishes a safe, encrypted channel between your Trezor® and browsers such as Chrome, Firefox, and Brave, keeping sensitive information fully protected from third parties.

Works with Popular Browsers

Installing Bridge allows browsers to detect and interact with your device, bypassing the restrictions most browsers have on direct USB access.

Runs in the Background

After installation, Bridge automatically runs in the background. There’s no need to start it manually — it activates whenever your Trezor® is connected.

Compatible Across Systems

Bridge supports Windows, macOS, and Linux, offering a smooth experience regardless of your operating system.

How to Install and Set Up

1 Begin Setup: Start by visiting trezor.io/start to configure your Trezor® device.

2 Automatic Check: When you connect your device through a browser, it will automatically ask you to install Bridge if it’s missing.

3 Install Bridge: Download and install Bridge for your OS. The setup usually completes in just a few minutes.

4 Restart Browser: After installation, restart your browser so it can detect the Bridge service.

5 Secure Connection: Once installed, Bridge allows you to proceed with your Trezor login directly in the browser.

Note: If you are using the desktop Trezor Suite app (Trezor Suite download), you don’t need Bridge, as Suite has its own drivers built-in.
