Trezor Bridge is a crucial communication tool that enables secure interaction between web browsers and Trezor® hardware wallets. Unlike the desktop Trezor Suite application that communicates directly with devices, web-based access requires this background service to translate browser requests into USB commands that your hardware wallet can understand and process securely.
Trezor Bridge maintains the fundamental security principle: private keys never leave your hardware device. It acts as a secure messenger that facilitates communication while keeping cryptographic operations isolated within your Trezor® device.
Converts web-based API calls into USB communication protocols that your Trezor® device can process, creating a seamless bridge between browser applications and hardware security.
Creates an encrypted communication channel between your browser and hardware wallet, ensuring data integrity and confidentiality during all interactions.
Runs as a background service that automatically activates when needed, requiring minimal user intervention once properly installed and configured.
When you first access the web version of Trezor Suite, the system will automatically detect if Trezor Bridge is missing and prompt you to download and install it.
If automatic installation fails, visit the official Trezor website and download Trezor Bridge directly. The installation process is straightforward and typically completes within minutes.
After installation, restart your browser. Trezor Bridge runs as a background service and automatically integrates with supported browsers without additional configuration.
Once installed, you can complete the Trezor Bridge Login process by connecting your device and accessing web-based Trezor services through your browser.
Windows 7+, macOS 10.11+, Linux (multiple distributions)
Chrome, Firefox, Edge, Brave, and other Chromium-based browsers
Trezor One, Trezor Model T, and all firmware versions
Restart your browser and ensure Trezor Bridge is running as a background service. Check system tray for the Bridge icon.
Try different USB ports, use original cables, and ensure no other cryptocurrency applications are interfering with the connection.
Update your browser to the latest version and ensure you're not using private/incognito mode, which may block necessary permissions.
Check firewall settings to ensure Trezor Bridge is allowed to communicate through your network security.
For users who prefer to avoid web-based access entirely, the desktop version of Trezor Suite provides direct device communication without requiring Trezor Bridge. This option offers enhanced privacy and eliminates potential browser-related compatibility issues.
Do I need Trezor Bridge if I use the desktop Trezor Suite application?
No, Trezor Bridge is only required for web-based access through browsers. The desktop Trezor Suite application communicates directly with your hardware wallet without requiring additional bridge software.
Is Trezor Bridge safe to install on my computer?
Yes, Trezor Bridge is developed and maintained by SatoshiLabs, the same company that creates Trezor hardware wallets. It's open-source software that only facilitates communication and doesn't handle private keys or sensitive data.
Why does my browser show a connection error even with Trezor Bridge installed?
This typically indicates that Trezor Bridge isn't running or your browser is blocking the connection. Restart both the Bridge service and your browser, and ensure your firewall isn't blocking the application.
Can I use Trezor Bridge with multiple browsers simultaneously?
Yes, Trezor Bridge works with all supported browsers on your system. However, you can only interact with one Trezor device at a time through a single browser tab.
Do I need to update Trezor Bridge manually?
Trezor Bridge includes automatic update functionality. However, if you experience connection issues, manually downloading and installing the latest version from the official website often resolves problems.
Is there a mobile version of Trezor Bridge?
No, mobile access uses different communication methods (OTG/USB). Mobile browsers and compatible apps handle device communication directly without requiring a separate bridge application.
