Trézor Bridge® is the official communication interface created by SatoshiLabs that allows the browser or desktop App to talk securely to your Trezor hardware wallet — without exposing your private keys. :contentReference[oaicite:1]{index=1}

🔍 Why You Need It

• Modern browsers block direct USB access; Bridge acts as a secure intermediary. :contentReference[oaicite:2]{index=2}
• Ensures compatibility with a wide range of operating systems and browsers. :contentReference[oaicite:3]{index=3}
• Provides encrypted, safe transport for instructions to and from your Trezor device. :contentReference[oaicite:4]{index=4}

💡 Key Point

Bridge does not store private keys or sensitive data — signing and critical confirmations happen on the device itself. :contentReference[oaicite:5]{index=5}

Follow these official steps to install Bridge on your system.

🔹 Step 1: Visit Official Link

Open the official installation portal: https://trezor.io/start and click on the Bridge download option. :contentReference[oaicite:6]{index=6}

🔹 Step 2: Choose Your OS

Select the version that matches your computer (Windows, macOS, or Linux) and download it. :contentReference[oaicite:7]{index=7}

🔹 Step 3: Run the Installer

Follow on-screen instructions. On macOS, approve the application in Security & Privacy if prompted. :contentReference[oaicite:8]{index=8}

🧠 Tip

If you have Trezor Suite installed, Bridge may already be bundled — but installing explicitly ensures browser compatibility. :contentReference[oaicite:9]{index=9}

🚀 Step 1: Launch Bridge

Once installed, Bridge runs in the background as a local service. You may see its icon in your system tray.

🚀 Step 2: Open the New Trezor App

In your browser, go to the official Suite Web App at https://suite.trezor.io. :contentReference[oaicite:10]{index=10}

🚀 Step 3: Connect via USB

Plug in your Trezor wallet with the official cable. Bridge should detect it instantly. :contentReference[oaicite:11]{index=11}

✔ Allow Access Prompt

When asked by the browser, grant permission to allow Bridge to communicate with your wallet. Always check the domain for correctness. :contentReference[oaicite:12]{index=12}

🛠 Architecture Overview

Bridge installs as a local service and listens on a loopback address (e.g. localhost:21325) for secure commands from your browser to your Trezor device. :contentReference[oaicite:13]{index=13}

🔒 Privacy & Security

• Bridge never sees or stores private keys — all signing is done on the hardware. :contentReference[oaicite:14]{index=14}
• Uses encrypted, local-only communication channels. :contentReference[oaicite:15]{index=15}

✔ Always Use Official Links

Download Bridge only from https://trezor.io/start or https://trezor.io/bridge. :contentReference[oaicite:16]{index=16}

✔ Verify All Prompts

Check the information on your Trezor device screen before confirming any transaction. :contentReference[oaicite:17]{index=17}

✔ Keep Software Updated

Always install the latest firmware and software updates to protect against vulnerabilities. :contentReference[oaicite:18]{index=18}

⚠ Never enter your recovery seed into any software — not even Bridge or the browser. :contentReference[oaicite:19]{index=19}

❗ Bridge Not Starting

Reinstall with Administrator rights or restart your computer. Check OS security settings for blocked permissions. :contentReference[oaicite:20]{index=20}

❗ Browser Doesn’t Detect Bridge

Reload the page or restart the browser. Make sure it allowed USB access. :contentReference[oaicite:21]{index=21}

❗ Outdated Bridge Version

Check for updates via Trezor Suite or the official download page: trezor.io/start. :contentReference[oaicite:22]{index=22}

Do I Need Bridge for Every Wallet?

For most browser-based wallets and apps, yes — Bridge ensures communication. For native desktop Suite apps, it may not be strictly required. :contentReference[oaicite:23]{index=23}

Does Bridge Have Access to My Keys?

No — your private keys never leave your device. :contentReference[oaicite:24]{index=24}
