Why trezor bridge matters

Trezor Bridge acts as a trusted mediator between your browser and the Trezor device. Modern browsers restrict direct USB access for security; Bridge restores secure, user-authorized connectivity so you can sign transactions and manage accounts.

How to install

  1. Visit the official page: trezor.io/bridge.
  2. Download the installer for Windows, macOS, or Linux and run it.
  3. Open your browser and connect your Trezor when prompted—no extension needed.

Troubleshooting

Common fixes: restart the Bridge service, try a different USB cable/port, disable conflicting browser extensions, or reinstall Bridge. For step-by-step help see Trezor Support.

Security & privacy

trezor bridge never accesses your seed or private keys. It only forwards encrypted communication between your Trezor device and trusted software. Always download Bridge from the official site and verify signatures when available.

Compatibility & alternatives

Bridge works with Trezor Suite and many web wallets. If you prefer, Trezor Suite (desktop app) can be used as an alternative connection path: trezor.io/start.

Quick FAQ

  • Do I need Bridge for all browsers? Mostly for Chrome/Firefox desktop to enable USB. Some wallets detect Suite automatically.
  • Is Bridge safe? Yes—it's a local-only application designed to minimize attack surface.
