Introduction — What is Trezor Bridge?
Trezor Bridge is a lightweight communication layer that allows your Trezor hardware wallet to talk to web applications and Trezor Suite via your browser. It replaces older browser plugins and creates a secure channel so the device can be detected, firmware updated, and transactions confirmed — while keeping private keys safely on the device.
Key benefits
- Works across Windows, macOS, and Linux 💻
- Enables secure browser communication with Trezor devices 🔐
- No sensitive data leaves the hardware wallet — keys remain offline 🗝️
- Streamlines firmware updates and recovery flows ⚙️
Before You Start — Requirements & Safety
What you need
- A compatible Trezor device (Model T / One)
- USB cable and a computer with an up-to-date browser (Chrome, Edge, Firefox)
- Access to trezor.io/start for official downloads
Safety checklist
- Download Bridge only from official Trezor pages — avoid third-party sites
- Never share your recovery seed — Trezor will never ask for it online
- Use a private, trusted network (avoid public Wi-Fi when setting up) 🌐
Step-by-Step Setup
Step 1 — Go to the official start page
Open trezor.io/start and choose your device model. The official site will offer the correct Bridge installer for your OS.
Step 2 — Download & install Trezor Bridge
Download the installer, run it, and follow the prompts. On macOS you may need to allow system permissions; on Linux you may need to run a package manager command — the official page includes platform-specific instructions.
Step 3 — Connect your Trezor
Plug your Trezor into USB. Open your browser and visit the Trezor web app or launch Trezor Suite. The browser should detect the device via Bridge and guide you to initialize or unlock it.
Step 4 — Initialize or recover
Follow on-screen prompts to create a new wallet (set PIN, write recovery seed) or recover an existing one. Confirm every action on the device screen — never enter your seed into the browser.
Troubleshooting
Common issue: Device not found
- Try a different USB cable (data-capable) and port.
- Restart the browser and Trezor Suite.
- Verify Bridge is running: on Windows check Services, on macOS check Activity Monitor.
Common issue: Permissions or driver errors
On some systems you must grant USB permissions. Follow the instructions from the official start page for your OS. On Linux, you may add udev rules provided by Trezor.
Advanced: Security & Best Practices
Keep firmware & software up to date
Firmware updates fix vulnerabilities and add features. Use Trezor Suite or the official web app to apply updates; verify update prompts and confirm everything on the device screen.
Backup your recovery seed securely
Write your recovery seed on the provided card or a metal backup. Store backups in safe, separate locations. Consider a split backup strategy if you need additional redundancy.
Use hardware confirmations
Always verify transaction details on your Trezor device display before approving. This is the final line of defense against malware and address-swapping attacks.
FAQ & Final Notes
Can I use Bridge with any browser?
Bridge works with major browsers (Chrome, Edge, Firefox). Some browsers may require additional permissions or settings; consult Trezor's official docs for compatibility notes.
Does Bridge send my keys anywhere?
No — Bridge only facilitates communication between your browser and the device. Private keys remain on the Trezor hardware at all times.
