🔐⚙️ Secure Connectivity Between Your Trezor Hardware Wallet and Your Browser
Trézor Bridge is the official communication software that enables your Trezor hardware wallet to connect securely with supported web browsers and online applications. If you plan to use Trezor Suite Web, interact with decentralized apps, or access third-party services that require hardware-wallet authentication, Trézor Bridge is the essential tool that makes it all possible.
This guide explains what Trézor Bridge is, how to install it, why it's important, and how to get started using it confidently and safely.
1. What Is Trézor Bridge?
Trézor Bridge is a lightweight background program created by SatoshiLabs, the makers of Trezor. Its job is to act as the secure communication layer between:
Your Trezor hardware wallet
Your web browser
Trezor Suite Web or compatible online apps
Modern browsers often restrict direct USB access for security reasons. Trézor Bridge solves this by providing a controlled, encrypted environment in which your wallet and browser can communicate safely.
It replaces older browser extensions and provides improved:
🔐 Security
⚡ Speed
🌐 Browser compatibility
🔧 Automatic updates
2. Why You Need Trézor Bridge
Not all browsers support WebUSB, and even those that do may have connection issues or limitations. Trézor Bridge ensures stable communication across all major browsers and operating systems.
You should install Trézor Bridge if:
You use Trezor Suite Web instead of the desktop app
Your browser has trouble detecting your device
You're using Linux or older macOS versions
You interact with Web3 platforms that support Trezor
You want consistent, reliable hardware-wallet connectivity
With Bridge installed, your browser will immediately recognize your Trezor when plugged in.
3. Downloading Trézor Bridge Safely
To avoid phishing or malicious downloads, always get the software from the official Trezor website:
➡ Visit: Trezor.io/bridge
➡ Select your operating system (Windows, macOS, Linux)
Never download Bridge from third-party sources or search engine ads. Unofficial installers may contain malware or attempt to steal your recovery phrase.
