Trezor Bridge is a dedicated communication tool developed by SatoshiLabs that enables secure connectivity between your Trezor® hardware wallet and web browsers. It acts as a background service that facilitates data exchange without compromising the security principles of your hardware wallet.
Unlike browser extensions that might have security vulnerabilities, Trezor Bridge operates as a standalone application that creates a secure channel between your Trezor® device and supported web browsers. This ensures that your private keys never leave your hardware wallet while still allowing you to interact with web-based cryptocurrency interfaces.
Creates an encrypted channel between your Trezor® device and web browsers, protecting your data from interception.
Runs silently in the background without requiring user intervention once installed.
Works with all major browsers including Chrome, Firefox, Edge, and Brave.
Maintains the fundamental security principle that private keys never leave your Trezor® device.
When you first connect your Trezor® device to your computer and visit a Trezor web interface like suite.trezor.io, the website will automatically detect if Trezor Bridge is missing and prompt you to install it.
If automatic installation doesn't work, you can manually download Trezor Bridge from the official Trezor website. Always ensure you're downloading from the official source to avoid security risks.
Run the installer and follow the on-screen instructions. The process is straightforward and typically requires just a few clicks.
After installation, restart your web browser to ensure it recognizes the newly installed Bridge.
The Trezor Bridge login process happens automatically. When you connect your device and visit a Trezor web interface, Bridge facilitates the connection without requiring separate credentials.
Trezor Bridge supports all major web browsers across different operating systems:
For the best experience, ensure you're using an updated version of your browser. Older versions may have compatibility issues with the latest version of Trezor Bridge.
Security Note: Trezor Bridge does not work with mobile browsers. For mobile access, use the dedicated Trezor Suite app available for iOS and Android devices.
While both options provide access to your Trezor® wallet, there are important differences:
Many users prefer the desktop application for regular use while keeping Bridge installed for occasional web-based access.
If you experience problems with Trezor Bridge:
If problems continue, consider using the desktop version of Trezor Suite, which doesn't require Bridge.
Is Trezor Bridge necessary if I use the desktop app?
No, the desktop version of Trezor Suite has built-in communication capabilities and doesn't require Bridge. Bridge is only needed for browser-based access.
Does Trezor Bridge work on mobile devices?
No, Trezor Bridge is designed for desktop operating systems. Mobile users should use the dedicated Trezor Suite app available for iOS and Android.
Can I use multiple Trezor devices with one Bridge installation?
Yes, a single Bridge installation can handle multiple Trezor devices, though you can only actively use one device at a time.
Is Trezor Bridge a security risk?
No, Trezor Bridge enhances security by creating a protected communication channel. It doesn't have access to your private keys, which always remain on your Trezor device.
Do I need to manually update Trezor Bridge?
Bridge typically updates automatically, but you may occasionally need to manually update it if you encounter compatibility issues with newer browser versions.
What should I do if Bridge isn't working after installation?
First, try restarting your browser and computer. If issues persist, reinstall Bridge or try using a different browser to determine if the problem is browser-specific.
