Accessing your cryptocurrency securely starts with trusted connections. Trézór Bridge is the communication layer that allows your computer browser to talk directly with your Trezor hardware wallet. Whether you're signing into your Trezor account via a web app or using third-party wallets, Bridge ensures seamless and encrypted communication between your browser and device.
Trézór Bridge is a small application that runs in the background of your operating system. It's required when using Trezor Suite Web or browser extensions like MetaMask to access your Trezor securely.
Think of Bridge as a translator — your web browser doesn't natively speak the "language" your Trezor understands. The Bridge ensures all messages (sign-ins, transaction approvals, address exports) are safely exchanged.
Visit the official site: trezor.io/bridge. This page will automatically detect your operating system and provide the correct installer.
Select your operating system (Windows, macOS, or Linux) and download the installer. Open it and follow the prompts to install.
Once installed, the Bridge will begin running silently in the background. You do not need to open it manually — it activates when needed by your browser.
After installing Trézór Bridge, completely close and reopen your browser. This ensures your web apps can detect the bridge service correctly.

Trezor doesn’t auto-update the Bridge. Visit the Bridge download page periodically to ensure you’re running the latest version.
If you wish to remove Bridge (e.g., switching to the desktop Suite), you can uninstall it like any normal program via your operating system’s apps or programs section.
