Trezor Bridge — Starting Up™ Your Device | Trezor®

Setting up a hardware wallet requires a secure connection between your Trezor device and the software you use to manage it. Trezor Bridge was created to provide that connection, allowing a computer to communicate with a Trezor hardware wallet and supported browser-based applications.

However, there is an important update for users looking for Trezor Bridge today: the standalone Trezor Bridge application has been deprecated by Trezor. Trezor now recommends using Trezor Suite and its current connection methods instead. Existing installations of standalone Bridge may interfere with future Trezor device connections, so Trezor recommends uninstalling the old software.

What Is Trezor Bridge?

Trezor Bridge was a background program designed to facilitate communication between a Trezor hardware wallet, Trezor Suite, and supported web browsers. Once installed, it could run in the background without requiring users to interact with it directly.

For many years, Bridge was an important component for connecting Trezor devices to browser-based applications. It helped provide a communication layer between the hardware wallet and software running on a computer.

Today, Trezor's ecosystem has evolved. Trezor Suite supports modern connection technologies, including WebUSB in compatible browsers, while the desktop and mobile applications provide additional connectivity options.

Is Trezor Bridge Still Required?

For most users, no. Trezor's current documentation states that standalone Trezor Bridge is deprecated and recommends uninstalling it. Keeping an old standalone installation on your computer may interfere with Trezor devices in future software releases.

Instead of searching for an old Trezor Bridge download, users should generally install the current version of Trezor Suite and follow the official setup instructions.

Trezor Suite is the primary interface for managing a Trezor hardware wallet. It allows users to connect their device, manage accounts, view portfolios, send and receive cryptocurrency, and access device settings.

Connecting Trezor Through the Web App

Trezor also provides a browser-based version of Trezor Suite. The current web application uses WebUSB to communicate with compatible Trezor devices.

To use the web app, open the official Trezor Suite web address in a supported Chromium-based browser. Trezor currently lists Chrome, Edge, Brave, and Opera among supported browsers. Firefox and Safari are not supported for this USB connection because they do not provide the required WebUSB functionality.

After opening Suite, connect your Trezor with a compatible USB data cable and follow the on-screen instructions. When the browser requests permission to access your device, approve the connection.

If the device is not detected, check that the cable supports data transfer rather than charging only.

Trezor Bridge and Device Setup

If you are setting up a new Trezor device, the easiest approach is to follow the official onboarding process rather than manually installing legacy connection software.

Start with Trezor.io/Start and download the current Trezor Suite application. Trezor's device guides explain that Suite guides users through connecting the hardware wallet, checking device authenticity, installing firmware, creating a wallet, and making a wallet backup.

This guided approach helps reduce confusion and ensures that users are working with the appropriate software for their device.

What If You Already Have Trezor Bridge Installed?

If you previously installed standalone Trezor Bridge, you may still see the program or its background process on your computer.

Trezor's official instructions explain how to remove the legacy software:

After removing the old Bridge installation, use the current Trezor Suite connection method recommended for your operating system and device.

For additional information, see the Trezor operating system and connectivity guide. It provides current information about supported operating systems, browsers, and device connections.

Desktop Suite vs. Web Suite

Trezor provides both desktop and web versions of Suite. The web version can be useful when installing software is not possible, while Trezor recommends the installed desktop application for everyday use because it offers additional functionality and performance benefits.

The desktop application also supports connection features that are not available through the web app. For example, Bluetooth connectivity on supported devices is handled through Trezor's desktop or mobile applications rather than the USB-only web application.

Choosing the appropriate version can therefore make setup and everyday wallet management easier.

Security When Connecting Your Trezor

Whether you are using Trezor Suite or another supported connection method, always verify that you are using official Trezor software and websites.

Pay particular attention to your wallet backup. Trezor states that Trezor Suite will never ask you to enter your wallet backup words into a browser or application. Backup words should be entered only on the Trezor device when an official recovery process requires it.

Never provide your backup words to someone claiming to be Trezor support. A website advertising a “Trezor Bridge download” or “Trezor support tool” should also be checked carefully before anything is installed.

Start Using Trezor the Modern Way

Although Trezor Bridge remains a familiar name among long-time Trezor users, the standalone application is now deprecated. Trezor recommends moving away from the legacy Bridge installation and using current Trezor Suite connectivity instead.

For a new device, begin with Trezor.io/Start, install the official Trezor Suite application, connect your hardware wallet, and follow the guided setup process.

If you need help with installation, connectivity, firmware, or other wallet functions, the Trezor Support and Guides section provides official documentation covering the current Trezor ecosystem.
