What is Trezor Bridge?

Trezor Bridge is a small background application developed by SatoshiLabs that facilitates communication between your Trezor® hardware wallet and your web browser. It acts as a secure bridge, allowing the Trezor Wallet interface—accessed via the web or Trezor Suite—to safely send and receive commands to your physical device without requiring any browser plugins.

Why Do You Need Trezor Bridge?

If you plan to manage your cryptocurrencies through a web browser using the wallet interface at trezor.io/start, Trezor Bridge is essential. It translates the browser's requests into a language your Trezor® device understands, enabling critical functions like Trezor login, transaction signing, and firmware updates. For users of the desktop application, the Trezor Suite app includes its own communication layer, often making Bridge unnecessary.

How to Download and Install Trezor Bridge

Follow these simple steps to get Trezor Bridge running on your computer:

  1. Visit the official Trezor® website: trezor.io/start.
  2. The page will automatically detect your operating system (Windows, macOS, or Linux).
  3. You will be presented with the option to download either Trezor Suite or Trezor Bridge. If you wish to use the web interface, select "Download Trezor Bridge."
  4. Run the downloaded installer file and follow the on-screen instructions.
  5. Once installed, restart your browser. Trezor Bridge runs silently in the background.

Direct Download Link: Download Trezor Bridge

Note: The modern and recommended way to interact with your Trezor® is through the Trezor Suite desktop application. A Trezor Suite download provides a more feature-rich and integrated experience, including built-in connectivity, and is generally preferred over the web interface and Bridge combination.

The Trezor Bridge Login Process

The term "Trezor Bridge Login" simply refers to the process of accessing your wallet via the web after Bridge is installed. Navigate to the Trezor Wallet interface, connect your device, and you will be prompted to enter your PIN directly on the Trezor® device screen—a secure process that never exposes your PIN to your computer.

Frequently Asked Questions (FAQ)

1. Is Trezor Bridge the same as the Trezor Suite?

No. Trezor Bridge is a lightweight communication tool for the web browser. Trezor Suite is a comprehensive desktop (and web) application for managing your crypto assets, which includes its own communication protocol.

2. Do I need Trezor Bridge if I use the Trezor Suite app?

Typically, no. The Trezor Suite app handles device communication internally. You only need Bridge if you are using the web-based wallet interface at wallet.trezor.io.

3. I installed Trezor Bridge, but my Trezor® is still not connecting. What should I do?

Try these steps: 1) Ensure your Trezor® is connected directly to your computer's USB port. 2) Restart your browser and computer. 3) Check if the Bridge process is running in your system tray/activity monitor. 4. Visit http://127.0.0.1:21325 in your browser; it should show a status message if Bridge is running.

4. Is Trezor Bridge safe to install?

Yes, provided you download it only from the official Trezor® website (trezor.io or suite.trezor.io). It is open-source software designed to enhance security by enabling safe communication.

5. Does Trezor Bridge work on Linux?

Yes, Trezor Bridge supports Windows, macOS, and most major Linux distributions. Installation instructions for Linux are available on the official Trezor® documentation.

6. Can I use my Trezor® without any software?

No. You need an interface like the Trezor Wallet (web) or the Trezor Suite application to view your portfolio, send and receive transactions, and manage settings. Your Trezor® device itself is a secure key storage and transaction signer.
