Trezor Bridge provides a safe, official channel between your Trezor hardware wallet and desktop web apps. It is engineered to reduce attack surface, keep cryptographic secrets off the internet, and make wallet integrations seamless for both newcomers and power users. Installation is lightweight and the connection is intentionally narrow: Bridge only talks to locally-attached Trezor devices and authorized browser sessions.

Frequently Asked Questions

1. Do I need Trezor Bridge to use my hardware wallet?
In most desktop browser scenarios you will install Bridge to create a secure local channel between the website and your device. Some wallet apps include native integrations that reduce the need for separate software, but Bridge remains the recommended official method for web-based connections.
2. Is Bridge safe to run continuously?
Yes — Bridge runs as a lightweight local background service and does not expose your keys to the network. It only responds to authorized local requests from web applications you approve.
3. Which platforms are supported?
Bridge provides installers for Windows, macOS, and Linux. Check the Downloads page for the latest packages and installation notes for each OS.
4. How do updates work?
Bridge checks for updates and will notify you; updating is explicit and controlled by you. Firmware updates for devices are separate and always require manual confirmation on the device itself.
5. I see an "untrusted origin" message — what should I do?
This means a web page requested access but wasn't recognized. Only grant access to sites you trust. If unsure, close the tab and review the website's documentation or contact support.
