Trezor Bridge is a essential communication tool developed by SatoshiLabs that enables secure connectivity between your Trezor® hardware wallet and web browsers. It acts as a facilitator that allows web applications to communicate with your Trezor® device without compromising security.
Unlike the Trezor Suite app which is a standalone application, Trezor Bridge operates in the background as a service that web browsers can access to establish a secure connection with your hardware wallet. This enables you to use your Trezor® device with web-based cryptocurrency platforms while maintaining the highest security standards.
Runs silently in the background without requiring user interaction once installed.
Establishes encrypted communication between your browser and Trezor® device.
Regularly updates itself to ensure compatibility with latest security protocols.
Works with Windows, macOS, and Linux operating systems.
Trezor Bridge is available for download from the official Trezor website. It's typically automatically prompted when you attempt to connect your Trezor® device to a web browser without Bridge installed. You can also manually download it from the Trezor support pages.
The installation process 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 without additional steps from the user.
Note: While Trezor Bridge enables web connectivity, for full functionality and enhanced security, consider completing the Trezor Suite download for the comprehensive desktop application experience.
Trezor Bridge is required in these specific scenarios:
Chrome, Firefox, Brave, and other Chromium-based browsers
Windows 8+, macOS 10.11+, Linux (Ubuntu 12.04+, Fedora 21+)
For new users setting up their device for the first time, visiting trezor.io/start will guide you through the process and determine if you need Trezor Bridge for your specific setup.
While both tools 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.
Do I need Trezor Bridge if I use the Trezor Suite app?
No, the Trezor Suite desktop 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?
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 security measures to protect your device and data.
Why won't my Trezor Bridge install properly?
Installation issues can be caused by browser extensions blocking the installation, security software interference, or incomplete downloads. Ensure you've downloaded the correct version for your operating system from the official website and temporarily disable security software if needed.
Can I use Trezor Bridge with multiple browsers?
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 runs automatically when needed. It typically starts when you connect your Trezor® device and try 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?
Trezor Bridge includes an automatic update mechanism that checks for and installs updates in the background. Manual updates can be performed by downloading the latest version from the Trezor website and reinstalling.
