Trezor Bridge — Official Download & Installation Guide

Why this guide matters

Using a hardware wallet correctly requires both the physical device and secure, official software to communicate with your computer. Historically Trezor Bridge served as the lightweight communication layer between a Trezor device and browsers or apps — but Trezor has shifted user flows toward the Trezor Suite app. This guide gives you an up-to-date path: official download links, installer steps, a deprecation note, and best practices for cold storage security.

Official download — where to get it

Always download Trezor software from the official Trezor pages. The two canonical starting points are:

• trezor.io/start — official “Get started” page and primary entry for new devices and software. :contentReference[oaicite:1]{index=1}
• data.trezor.io/bridge/latest — direct index of Bridge packages for Windows, macOS and Linux. :contentReference[oaicite:2]{index=2}

Installation & setup — step-by-step

Pre-installation checklist

• Confirm you are on trezor.io/start.
• Use the official installer matching your OS (Windows .exe, macOS .dmg, Linux .deb/.rpm or AppImage).
• Prefer a direct USB port (avoid hubs) and keep your device’s box and recovery card ready.

Windows / macOS / Linux — basic flow

1. From the official page, choose the Bridge package for your OS or download Trezor Suite. :contentReference[oaicite:4]{index=4}
2. Run the installer and follow on-screen instructions. On macOS you may need to allow the installer in System Preferences > Security & Privacy.
3. Restart your browser after installing Bridge so it can register background services.
4. Open Trezor Suite (or the browser flow at trezor.io/start) and plug in your device. The Suite may bundle Bridge functionality so a separate Bridge install can be unnecessary. :contentReference[oaicite:5]{index=5}
5. Follow the Suite’s setup wizard: initialize device, set a PIN, and write down the recovery seed on the physical backup card. Never store the seed digitally.

# Example: verify downloaded installer (Windows)
# Right-click the installer → Properties → Digital Signatures → verify 'SatoshiLabs' (official signer)

Security reminder: do not download Trezor Bridge from third-party mirrors or links received in chat/e-mail. Always verify trezor.io as the origin. :contentReference[oaicite:6]{index=6}

Deprecation & modern alternative

Important: Trezor has officially announced deprecation/removal of the standalone Trezor Bridge in favor of the integrated Trezor Suite app and modern browser integrations. If you are a new user, prefer installing the latest Trezor Suite (desktop) or following the official browser flow at trezor.io/start. If you have legacy workflows that require standalone Bridge, follow the deprecation guide and uninstall instructions on the official site. :contentReference[oaicite:7]{index=7}

Troubleshooting — common issues & fixes

• Device not detected: Try a different USB port and cable; plug into the computer directly (no hub); ensure Bridge or Suite is running. :contentReference[oaicite:9]{index=9}
• “Bridge not running” message: Restart your browser and confirm the Bridge service is active; reinstall Bridge only from the official index if required. :contentReference[oaicite:10]{index=10}
• Browser blocked extension/port: Check firewall/antivirus settings and allow local loopback or Bridge service through the firewall.
• Prefer desktop app: Install Trezor Suite; it often handles device connection without a separate Bridge install. :contentReference[oaicite:11]{index=11}

Security & best practices (cold storage focus)

• Record the recovery seed by hand and store it offline in multiple safe locations (paper + metal backup if possible).
• Never enter your recovery seed into software, browser, cloud storage or photos.
• Confirm every transaction on the device screen — the hardware wallet is the ultimate source of truth for addresses and amounts.
• Keep the firmware updated only via official Trezor Suite prompts; verify signatures if you manually download updates. :contentReference[oaicite:12]{index=12}

Frequently Asked Questions (FAQ)

1. Is Trezor Bridge still required?

Answer: For many users the Trezor Suite now bundles necessary communication layers and is the recommended path. Standalone Bridge is being deprecated for most users — check the official deprecation notice before installing a separate Bridge package. :contentReference[oaicite:17]{index=17}

2. Where do I download the official Bridge installer?

Answer: The canonical index for Bridge packages is available at data.trezor.io/bridge/latest; however, prefer installing the official Trezor Suite from trezor.io/trezor-suite. :contentReference[oaicite:18]{index=18}

3. My browser says Bridge not running — what do I do?

Answer: Restart your browser, confirm that Bridge or Trezor Suite is running, try another USB port/cable, and ensure firewall/antivirus is not blocking local Bridge services. If using the Suite app, try updating it. :contentReference[oaicite:19]{index=19}

4. Will installing Bridge expose my private keys?

Answer: No. Bridge is only a communication layer — private keys remain inside the Trezor device’s secure element and are never exposed to your computer or the Bridge service. Still, only use official downloads and verify sources. :contentReference[oaicite:20]{index=20}

5. Where can I get official help if something goes wrong?

Answer: Use the official Trezor guides and support routes at trezor.io/guides and product updates pages. Avoid third-party promises to “recover” seeds — they are frequently scams. :contentReference[oaicite:21]{index=21}
