Download Trézór Bridge®™ for Safe Crypto Access

If you’re setting up a Trezor hardware wallet or reconnecting to your crypto accounts through a browser interface, you may have been prompted to download Trezor Bridge. This companion app is essential for enabling secure communication between your browser and your Trezor device.

Understanding Trezor Bridge

Before we dive into the download process, it’s helpful to understand what Bridge does. Trezor Bridge is a minimalist, locally running application that operates as a communication bridge — hence the name — between your web interface or wallet app and your Trezor hardware wallet. Modern browsers often block direct USB access for security reasons, and Bridge solves that by acting as a trusted intermediary.

Here’s why it matters:

  • Enables browsers to detect your Trezor device over USB.
  • Provides encrypted communication between your system and the hardware wallet.
  • Keeps private keys on the hardware device, where they belong — Bridge never stores or transmits them.

Because Bridge handles USB communication securely and consistently across Windows, macOS, and Linux, it’s a cornerstone of most web‑based wallet experiences.

How to Download Trezor Bridge

Follow these steps for a secure download and install:

  1. Go to the official Bridge page: Open your web browser and type trezor.io/bridge into the address bar. This will lead you to the official download page.
  2. Select your platform: You’ll see download options tailored to your operating system — choose the one that corresponds to your computer:
    • Windows
    • macOS
    • Linux
  3. Download the appropriate installer: Click the button for your OS and wait for the file to download.
⚠️ Important: Always download Bridge from the official Trezor website. Avoid third‑party or unofficial mirrors, which might host malicious installers.

Installation Instructions

Once you have the installer:

  • Windows: Double‑click the .exe file. Follow the setup wizard, accept the license agreement, and grant necessary permissions.
  • macOS: Open the downloaded .dmg, drag the Bridge app into your Applications folder, and launch it. You may need to approve security permissions in System Preferences if macOS blocks the app.
  • Linux: Install using the provided package file (.deb, .rpm) or your distro’s package manager. If required, start the service manually.

After installing Bridge, restart your browser to ensure it can detect the newly installed background service.

First‑Time Setup & Device Connection

Now that Bridge is installed and running:

  1. Connect your Trezor device via USB.
  2. Open the Trezor Suite Web, another compatible wallet, or visit the Trezor setup page.
  3. Your browser should detect the Bridge and prompt you to allow access to your device. Follow the on‑screen instructions.

When performing actions like sending crypto or updating firmware, always verify all details on the physical Trezor device screen — that ensures security even if your computer environment is compromised.

Troubleshooting Common Issues

Even after installing Bridge, you might run into problems:

  • Browser still doesn’t detect Bridge:
    • Restart the browser or your computer.
    • Make sure firewall or security software isn’t blocking Bridge.
  • Device not recognized:
    • Try a different USB port or high‑quality USB cable.
    • Ensure Bridge is running (it runs silently in the background).
  • Installation errors:
    • On macOS, check Security & Privacy settings to allow the app.
    • On Windows, run the installer with administrator permissions.

Security Best Practices

Your Trezor hardware wallet is secure by design, and Bridge helps maintain that security. Follow these tips:

  • Download only from the official site: trezor.io.
  • Keep Bridge and Trezor firmware updated.
  • Confirm all actions on your Trezor device.

Installing Trezor Bridge correctly ensures a smooth, secure, and reliable connection between your Trezor device and your wallet software — letting you manage your crypto with confidence.
