Trezor Bridge – Secure Connection Between Your Trezor Wallet and Browser
Welcome to the complete guide for Trezor Bridge, the essential communication layer that connects your Trezor hardware wallet to supported browsers and desktop applications. If you use a Trezor wallet to manage cryptocurrencies, store digital assets, or authenticate with secure apps, Trezor Bridge ensures your device and computer communicate seamlessly and safely.
Whether you are setting up your Trezor for the first time or troubleshooting a connection issue, this page will walk you through everything you need to know—from installation steps and supported systems to features, security tips, updates, and best practices.
What Is Trezor Bridge?
Trezor Bridge is a lightweight software application that allows web browsers and desktop apps to communicate directly with your Trezor hardware wallet. Since most browsers no longer support USB communication by default, Trezor Bridge works as a secure middleware, enabling:

Secure app interactions
Without Trezor Bridge, your computer may not recognize your Trezor device properly, making it impossible to use web portals such as Trezor Suite Web.
