Trezor Bridge is a specialized communication tool developed by SatoshiLabs that enables web browsers to securely interact with your Trezor® hardware wallet. It serves as a vital link between web-based cryptocurrency applications and your physical device, ensuring that your private keys never leave the secure environment of your Trezor®.
Unlike the Trezor Suite app, which is a comprehensive desktop application, Trezor Bridge operates silently in the background as a local service. It facilitates the Trezor Bridge login process by translating browser requests into commands that your Trezor® device can understand and respond to, all while maintaining the highest security standards.
Establishes an encrypted connection between web browsers and your Trezor® device, ensuring all data remains protected.
Runs as a silent service without requiring user interaction once properly installed and configured.
Enables Chrome, Firefox, Brave, and other Chromium-based browsers to communicate with your hardware wallet.
Maintains itself with regular updates to ensure compatibility with the latest security protocols and browser versions.
When you first attempt to connect your Trezor® device to a web browser, you'll typically be prompted to download Trezor Bridge automatically. You can also manually download it from the official Trezor website or during the setup process at trezor.io/start.
The installation is straightforward:
Once installed, the Trezor Bridge login process becomes seamless. When you visit a supported web wallet and connect your Trezor® device, Bridge facilitates the connection automatically. You'll simply need to confirm actions physically on your device as you would with the Trezor Suite app.
Note: While Trezor Bridge enables web connectivity, for the most secure and feature-rich experience, consider completing the Trezor Suite download for the comprehensive desktop application.
Trezor Bridge is essential in these specific scenarios:
Chrome, Firefox, Edge, Brave, and other Chromium-based browsers
Windows 8+, macOS 10.11+, Linux (Ubuntu, Fedora, etc.)
While both facilitate Trezor login processes, they serve different purposes:
Many users install both applications: Trezor Bridge for web compatibility and Trezor Suite for regular wallet management and enhanced security features.
Do I need Trezor Bridge if I use the Trezor Suite desktop app?
No, the Trezor Suite application communicates directly with your Trezor® device without requiring Trezor Bridge. Bridge is only necessary for browser-based access to your wallet.
Is Trezor Bridge safe to install on my computer?
Yes, when downloaded from the official Trezor website, Trezor Bridge is completely safe. It's developed and maintained by SatoshiLabs, the creators of Trezor®, and includes multiple security measures to protect your device and data.
Why is my Trezor Bridge not working after installation?
Common issues include browser extensions blocking connectivity, security software interference, or incomplete installation. Try restarting your browser and computer, ensuring you've downloaded the correct version for your operating system, and temporarily disabling security software if needed.
Can I use Trezor Bridge with multiple browsers simultaneously?
Yes, once installed, Trezor Bridge works with all supported browsers on your computer. You don't need to install it separately for each browser.
Do I need to keep Trezor Bridge running at all times?
Trezor Bridge typically starts automatically when needed. It launches when you connect your Trezor® device and attempt to access a web wallet that requires it. You can configure it to run on system startup if you frequently use web-based wallets.
How do I update Trezor Bridge to the latest version?
Trezor Bridge includes an automatic update mechanism that checks for and installs updates in the background. For manual updates, download the latest version from the official Trezor website and reinstall.
