Trezor Bridge — simple desktop link for Trezor wallets

A short, practical guide to installing, using and troubleshooting "Trezor Bridge" — the small bridge app that lets your desktop browser or wallet connect to your Trezor device securely.

What is Trezor Bridge?

"Trezor Bridge" is a lightweight local application that creates a secure channel between your Trezor hardware wallet and desktop applications (for example Trezor Suite or browser-based wallets). It runs on your machine and handles communication so websites don't need direct USB access.

Why it matters

  • Improves compatibility with browsers and desktop wallets.
  • Isolates USB communication to a trusted local process.
  • Keeps your hardware wallet interactions user-friendly and secure.

Install & setup (quick)

  1. Download the official Trezor Bridge installer for your OS from the official source (Windows, macOS, Linux).
  2. Run the installer and accept system prompts (you may need admin rights).
  3. Open your desktop wallet or compatible browser page; the site should detect the bridge automatically.
  4. If the browser asks to connect to your Trezor, confirm on the device and in the app.

Tip: If you see prompt errors, restart the bridge service or your browser before trying again.

Security tips

  • Only download Trezor Bridge from official Trezor sources.
  • Keep your Trezor firmware and desktop apps up to date.
  • Never share your recovery seed; Trezor Bridge only handles device communication, not secrets.

Quick commands

sudo service trezord start   # (linux example)
# Or restart: sudo service trezord restart

Troubleshooting

  1. Device not detected: Try a different USB cable or port. Use a direct port (avoid hubs).
  2. Permission errors: On macOS/Windows run the installer with admin rights; on Linux check udev rules.
  3. Browser still won't connect: Close and reopen the browser, or fully quit & relaunch Trezor Suite.
  4. Bridge service stopped: Restart the bridge or reboot the computer.

Frequently asked

Is Trezor Bridge safe?

Yes — when downloaded from official sources, it acts as a local relay. It does not transmit your seed. Treat it like any other software: keep it updated and verify downloads.

Can I use Trezor without the Bridge?

Some older setups or web-based solutions might use direct USB access, but the bridge improves compatibility across modern browsers and platforms.

Where to get updates?

Check your wallet's official download page or the Trezor website for the latest Bridge releases and release notes.
