Trezor Bridge® | Connect Your Trezor to Web Browsers
🔗🔐 Secure, Seamless, and Fast Connectivity for Your Hardware Wallet
Trezor Bridge® is the official communication tool that allows your Trezor hardware wallet to interact securely with supported web browsers and online applications. Whether you're using the Trezor Suite Web, third-party wallets, or decentralized apps, Trezor Bridge ensures your device connects safely and smoothly without exposing your private keys.
This guide explains what Trezor Bridge is, why it’s essential, how to install it, and how it enhances your overall crypto security experience.
1. What Is Trezor Bridge®?
Trezor Bridge® is a lightweight background service that creates a secure communication channel between your Trezor hardware wallet and your browser. Without Bridge, most browsers cannot detect or interact with the device.
It was designed to replace older browser extensions and ensure:
Faster communication
Stronger security
Broader compatibility
Automatic updates
A plug-and-play user experience
Trezor Bridge is particularly important for users who prefer using Trezor Suite Web, browsers that do not support native USB communication, or third-party blockchain apps.
2. Why You Need Trezor Bridge
Not all modern browsers support direct USB or HID (Human Interface Device) connections.
Trezor Bridge solves this by acting as a secure middleware layer between:
👉 Your Trezor device
and
👉 Your browser-based wallets and services
You need Trezor Bridge if:
You want to use Trezor Suite Web
Your browser doesn’t support WebUSB
You interact with third-party Web3 apps
You use Linux or older operating systems
You experience connection issues without it
It guarantees a consistent experience across devices and browsers.
3. Where to Download Trezor Bridge
To ensure security, always download Trezor Bridge from the official Trezor website:
➡ Visit Trezor.io/bridge
➡ Then select your operating system (Windows, macOS, Linux)
Avoid downloading the software from unofficial sources.
Fake versions can steal your recovery seed, compromise your device, or install malware.
4. Installing Trezor Bridge
Installation takes only a few minutes.
Step-by-step installation:
Download the installer from the official site
Run the installation file

5. Connecting Your Trezor Using Bridge
After installing Trezor Bridge:
