What is Trezor Bridge?
Trezor Bridge is (or historically was) a small background app that helps your browser or desktop app talk to a Trezor hardware wallet. It acts like a secure connector between the device and web pages or Trezor Suite so you can manage crypto safely from your computer.
- Purpose: enable communication between Trezor hardware and host software.
- Runs: as a background service (Windows / macOS / Linux).
- Alternatives: Trezor Suite and WebUSB can also be used depending on platform and security preferences.

Install & quick steps
Prefer official sources only. Typical steps (overview):
- Visit the official Trezor website or Trezor Suite download page.
- Download the installer for your OS and run it.
- After install, plug your Trezor and follow on-screen prompts to connect.
If you already use Trezor Suite, recent Suite releases may incorporate the connection functionality — standalone Bridge has been deprecated in favor of updated Suite workflows on some platforms.
Security notes
Short, practical guidance:
- Only download installers from the official trezor.io site or the project's official GitHub releases.
- Verify signatures where provided before installing.
- Uninstall older standalone Bridge versions when migrating to the latest Trezor Suite if instructed by official docs.
Developer & integration tips
WebUSB
Modern browsers (Chrome) can use WebUSB to connect directly to Trezor without Bridge on supported platforms.
Background service
When installed, Bridge typically runs as a small background process (names like trezord appear in system monitors).
Compatibility
Works with Trezor Suite, some web wallets, and other compatible apps that request device access.
