Trezor Bridge is the essential communication software that enables secure interaction between your Trezor® hardware wallet and web browsers. This background service acts as a secure bridge, facilitating data transmission while ensuring your private keys never leave the hardware device. Unlike traditional USB drivers, Trezor Bridge provides enhanced security and compatibility across different platforms and browsers.
Trezor Bridge serves multiple critical functions in the Trezor® ecosystem:
Most users get Trezor Bridge automatically during the Trezor Suite download process. This is the recommended method for seamless integration.
For specific needs, Trezor Bridge can be downloaded separately from the official Trezor® website, though this is rarely necessary.
Linux users can install via package managers like APT or YUM, ensuring automatic updates through system repositories.
When you complete the Trezor Suite download, Trezor Bridge is automatically installed and configured. This integration ensures that when you perform Trezor login through Trezor Suite, the communication layer is already established and secured. The bridge works seamlessly with both the desktop application and web interface of Trezor Suite.
It's important to note that the Trezor Suite app for mobile devices doesn't require Trezor Bridge. Mobile platforms use different communication protocols, and the Trezor Suite app is designed to work natively with mobile operating systems without additional bridge software.
For new users, the complete setup process begins at trezor.io/start, which automatically checks for and installs the necessary components, including Trezor Bridge. This ensures your Trezor Wallet communication is properly configured from the very beginning.
In most cases, no. Trezor Bridge is automatically installed during the Trezor Suite download process. Separate installation is only necessary for specific edge cases or troubleshooting connection issues.
Trezor Bridge provides enhanced security features, better browser compatibility, and automatic updates that standard USB drivers cannot offer. It creates a secure communication channel specifically designed for cryptocurrency operations.
No, the Trezor Suite app for mobile devices uses different communication protocols and doesn't require Trezor Bridge. The bridge is specifically designed for desktop browser communication.
First, try restarting the application. If issues persist, reinstalling Trezor Suite typically resolves bridge-related problems. The Trezor Suite download includes the latest bridge version.
Trezor Bridge supports Windows 10+, macOS 10.14+, and most modern Linux distributions. It's automatically configured for your specific operating system during installation.
For web browser access, Trezor Bridge is essential. However, the desktop Trezor Suite application can sometimes communicate directly with devices, though bridge installation is still recommended for full functionality.
