Trezor Bridge is the essential communication software that enables secure interaction between your Trezor® hardware wallet and web browsers. Unlike standard USB drivers, this specialized background service creates a secure, encrypted channel for data transmission while ensuring your private keys never leave the hardware device. It's a critical component that facilitates the Trezor login process and all wallet operations through web interfaces.
Encrypted data exchange between browser and hardware device
Works with Chrome, Firefox, Edge, and other major browsers
Runs silently in background without user intervention
Available for Windows, macOS, and Linux systems
When you complete the Trezor Suite download, Trezor Bridge is automatically installed and configured. This seamless integration ensures that when you access your Trezor Wallet through Trezor Suite, the communication layer is already established and secured. The bridge works with both the desktop application and web interface, providing consistent performance across all access points.
Bridge's Role in Authentication: During Trezor login, the bridge facilitates the secure handshake between your browser and hardware device. It transmits the randomized PIN matrix to your computer screen and relays your device responses back to the browser, all while maintaining complete isolation of your private keys.
For most users, Trezor Bridge installation happens automatically during the Trezor Suite download process. New users starting at trezor.io/start will have the bridge installed as part of the initial setup procedure. The installation is typically quick and requires no user configuration.
The Trezor Suite app for mobile devices doesn't require Trezor Bridge, as mobile platforms use different communication protocols. The mobile app is designed to work natively with iOS and Android operating systems, providing a streamlined experience without additional bridge software.
No, Trezor Bridge is automatically installed during the Trezor Suite download process. Separate installation is only necessary in rare cases where automatic installation fails or for specific troubleshooting scenarios.
