How it works
Trezor Bridge runs on your computer and exposes a secure local API that the browser-based Trezor Suite or other supported web apps use to talk to the hardware device. Instead of relying on direct USB access from the browser, Bridge provides a controlled, authenticated channel that improves compatibility across browsers and operating systems.
Why it matters
- Compatibility: Makes Trezor devices work reliably with modern browsers.
- Security: Keeps device communication local and explicit — approvals still happen on the hardware.
- User experience: Simplifies the setup for interacting with web-based wallets and services.
Quick tips
If a web app asks for access, always confirm actions on your Trezor device. Keep your Bridge installation updated from official sources and use only trusted websites when managing funds.
Note: "Trezor Bridge" is the local helper — it does not store seeds or private keys; those remain secured on your Trezor device.
