01 / CONTEXTUNDERSTANDING THE LINK

A small bridge.
A clearer connection.

Trezor Bridge is a communication utility designed to help a computer connect with a Trezor hardware wallet when compatible wallet management software needs it. It works in the background: Bridge is the link between the browser-based experience and your plugged-in device, not a replacement wallet or a place to manage funds on its own.

Whether you are setting up for the first time or diagnosing a device that is not appearing, the right steps depend on your operating system and the software you use. Product requirements can change, so use current official guidance rather than old instructions saved elsewhere.

02 / FUNCTIONTHE CONNECTION LAYER

How Trezor Bridge Supports
Device Connectivity.

Four useful things to know before you troubleshoot.

01↗

Browser communication

Bridge acts as a local communication layer that helps compatible browser-based wallet software talk to a connected Trezor device.

02↗

Device recognition

When the supported setup is in place, wallet software can detect a connected device and present the next available connection steps.

03↗

Compatibility context

Requirements depend on your operating system, browser, device and wallet software. Check Trezor’s current compatibility guidance before changing your setup.

04↗

A clearer troubleshooting path

A connection checklist helps isolate common causes—cable, browser permissions, software versions or an outdated setup—without guessing or installing unofficial tools.

Availability and installation requirements are determined by the wallet software and platform in use. Refer to official documentation for the latest details.

03 / PROCESSFOLLOW THE SOURCE

Set up from
verified instructions.

A safe setup begins with the right source—not a search result or a download link from a stranger.

Open Trezor Start ↗
  1. 01

    Start at the official source

    Type trezor.io/start into your browser or use the official Trezor Help Center. Verify the domain before proceeding.

  2. 02

    Identify your device and platform

    Choose the instructions that match your Trezor model, operating system and intended wallet software. Do not assume an older guide still applies.

  3. 03

    Follow the supported setup flow

    Install or update software only when official instructions direct you to. Use a reliable data-capable cable, connect the device and follow on-screen prompts.

  4. 04

    Confirm before troubleshooting

    If recognition fails, check cable, port, browser permissions and software status. Consult current official troubleshooting steps before trying additional utilities.

04 / SECURITYPAUSE BEFORE YOU INSTALL

Trust the source.
Protect the setup.

Look closely at the web address and use official Trezor pages for installation details. Avoid sponsored lookalikes, unofficial download mirrors, unsolicited support messages and files sent through chat or email. Never share your recovery seed with a website, support agent or software prompt. Trezor will not need your seed to make Bridge work.

If a page asks for sensitive recovery information or pressures you to install an unexpected file, stop and navigate directly to Trezor’s official site instead.

05 / QUICK ANSWERSCOMMON QUESTIONS

Good to
know.

What is Trezor Bridge?+

It is software that enables communication between a computer and a Trezor device for compatible wallet management software. It is not itself a wallet or a place where coins are stored.

Do I always need to install Bridge?+

Not necessarily. The required connection method can vary by wallet software, browser and platform. Follow the current instructions shown by Trezor or the wallet you intend to use.

Why is my Trezor device not detected?+

Try a data-capable USB cable and another port, unlock and reconnect your device, and check the browser prompt. Then review official troubleshooting guidance and confirm your software is current.

Where can I find safe setup instructions?+

Start from trezor.io/start or Trezor’s Help Center. Check the address carefully and do not follow download links from unsolicited messages, ads or unofficial mirrors.
