Trezor Bridge — Starting Up Your Device | Trezor®

Getting started with a Trezor hardware wallet is designed to be straightforward. When you connect your device for the first time, Trezor Suite guides you through the setup process, device verification, firmware installation, and wallet backup. For users searching for Trezor Bridge, it is important to understand how device communication works today and how Trezor Suite fits into the process.

Trezor Bridge was originally developed to help establish communication between a Trezor device, Trezor Suite, and supported web browsers. However, standalone Trezor Bridge is now deprecated. Trezor recommends removing an older standalone Bridge installation if it is still present on your computer, as it may interfere with newer releases.

Starting Up Your Trezor Device

To begin, download Trezor Suite from the official Trezor website and install the application on your computer. Trezor recommends using Trezor Suite for the best experience when setting up a new device. You can also use the Trezor Suite web application with a compatible browser when appropriate.

Once Trezor Suite is open, connect your Trezor device using the appropriate USB cable. The software will guide you through the initial connection and security checks. Depending on your device and setup, you may be asked to install the original Trezor firmware before continuing.

Do not disconnect the device while firmware installation is in progress. Allow the process to finish and follow the instructions displayed by Trezor Suite.

Why Device Communication Matters

A hardware wallet needs a secure way to communicate with the software used to manage it. Historically, Trezor Bridge provided this connection between the hardware device and compatible browsers. Today, Trezor Suite handles the modern connection experience, while browser-based use can also rely on supported technologies such as WebUSB.

If you are using an older computer that still has standalone Trezor Bridge installed, check whether it is necessary. Trezor states that the standalone version is deprecated and recommends uninstalling it where applicable. This can help prevent conflicts when using newer versions of Trezor Suite.

Verify Your Trezor Before Continuing

Security should be part of the setup process from the beginning. Trezor recommends purchasing devices through the official Trezor Shop, its Amazon storefront, or authorized resellers. A new device should also be checked for signs of tampering before use.

During setup, Trezor Suite performs security-related checks and guides you through the device initialization process. Trezor devices are distributed without firmware installed, and the setup process checks the firmware before allowing normal use.

For additional information, see the official Trezor security and privacy guides.

Set Up Your Wallet Backup

After the device has been connected and verified, Trezor Suite guides you through creating your wallet backup. This backup is a critical part of using a self-custody hardware wallet because it allows the wallet to be recovered if the physical device becomes unavailable.

Keep your wallet backup private and secure. Never share your backup words with another person or enter them into an unfamiliar website, application, form, or message. Trezor provides additional information about wallet backups in its wallet backup guide.

What If Trezor Suite Does Not Detect Your Device?

If your Trezor is not detected, first check the physical connection. Make sure the cable is properly connected and, when using a browser-based setup, ensure that you are using a compatible browser and a data-capable cable.

For the Trezor Suite web application, Trezor currently supports Chromium-based browsers such as Chrome, Edge, Brave, and Opera. Firefox and Safari do not support the WebUSB functionality required for this browser-based connection.

If you previously installed standalone Trezor Bridge, consider removing it according to Trezor's instructions. Older Bridge installations can interfere with newer versions of Trezor software.

You can also review the official Trezor device troubleshooting guide for connection and firmware-related issues.

Start Using Trezor Suite

Once your device has been verified and initialized, Trezor Suite provides the interface for managing your supported crypto assets. The current setup process is centered around Trezor Suite rather than requiring users to manually manage an older standalone Trezor Bridge installation.

If you are beginning with a new Trezor, the easiest approach is to start at the official Trezor Get Started page, download Trezor Suite, connect your device, and follow the instructions shown on screen.

Remember that security begins with obtaining your device from a trusted source and continues throughout the setup process. Keep your wallet backup protected, follow the instructions displayed on your Trezor device, and use official Trezor resources whenever you need help.

Official Trezor Resources

For setup and ongoing support, use official Trezor documentation rather than downloading old or unofficial Bridge software. The Trezor Learn center contains guides covering security, wallet backups, supported assets, and other aspects of using a Trezor hardware wallet.

The key point is simple: if you searched for “Trezor Bridge starting up your device,” you may be looking for the older connection method. For current setups, begin with Trezor Suite and follow the official setup instructions. If standalone Trezor Bridge is already installed, check Trezor's deprecation guidance before continuing.
