Trezõr® Bridge® | Sign In Your Device

Welcome to Trezõr® Bridge®

Trezor Bridge is the communication interface that allows your Trezor hardware wallet to interact with your browser and desktop applications, like Trezor Suite. Without Bridge, your device cannot securely connect to web wallets or desktop environments.

        What is Trezor Bridge? – It's a small background application that acts as a bridge between your Trezor and computer.
      

Why You Need Trezor Bridge

Unlike browser extensions or plug-ins, Trezor Bridge offers a deeper level of trust and compatibility with all major platforms. It works independently of Chrome, Firefox, Safari, or any browser, and allows your device to sign and verify transactions securely.

Securely connect your device to Trezor Suite or Web Wallet
Access signing functionality and data transfer
Avoid browser-based security limitations
Works silently in the background

Trezor Bridge replaces the older Chrome extension. It’s now the recommended method to connect your device.

Step 1: Download Trezor Bridge

Start by visiting the official site: https://trezor.io/bridge/

Choose the version for your OS:

Windows (.exe)
macOS (.dmg)
Linux (.tar or .deb)

⚠️ Only download Trezor Bridge from the official trezor.io domain to avoid malware or phishing risks.

Step 2: Install Trezor Bridge

Follow these installation instructions:

Double-click the downloaded file
Run the installer and allow it to make changes to your system
After installation, restart your browser
Trezor Bridge will now run in the background automatically

You won't see a window for Bridge — it's a background service.

Step 3: Connect Your Trezor

Once Trezor Bridge is running, plug in your Trezor Model T or Trezor Model One using a USB cable. Open Trezor Suite or visit wallet.trezor.io.

You will see a prompt to "Connect Device" or "Allow Trezor Bridge". Confirm this on your computer.

✅ On your Trezor device, confirm physical authorization when prompted.

Step 4: Sign In & Authorize

When signing in, Trezor Bridge ensures that all authentication actions are confirmed via physical interaction on the Trezor device.

This protects you from phishing and remote attacks. Each operation must be approved on-screen.

View addresses
Sign transactions
Authorize apps (e.g., Metamask via WebUSB)

Bridge also works with third-party services like Uniswap, Aave, or Electrum when supported.

Troubleshooting Tips

Restart your browser after installation
Clear browser cache if device is not detected
Ensure USB cable is data-capable (not just charging)
Use original firmware and official device
Check for Bridge updates regularly

Advanced Usage: WebUSB Mode

If you prefer not to install Bridge, some platforms support WebUSB, allowing direct browser connection. However, Bridge is still more stable and widely supported.

Note: WebUSB is supported in Chrome and Chromium-based browsers only.

Security & Privacy Considerations

Trezor Bridge does not collect any user data. It simply passes commands from your device to Trezor Suite or the web wallet. All sensitive actions (like signing or verifying addresses) happen strictly on the hardware device.

No telemetry
No cloud interaction
