Trezor Bridge is an essential background service that enables secure communication between your Trezor hardware wallet and supported web applications. It acts as a trusted connector, allowing browsers to recognize your Trezor device while keeping your private keys completely offline.

If you use web-based wallets, exchanges, or blockchain services with your Trezor, Trezor Bridge ensures that every interaction remains safe, verified, and protected from unauthorized access.

What Is Trezor Bridge?

Trezor Bridge is lightweight software installed on your computer that allows your web browser to communicate with your Trezor hardware wallet. Since modern browsers restrict direct USB access for security reasons, Trezor Bridge acts as a secure intermediary.

It does not store private keys, wallet data, or recovery seeds. Its only role is to enable safe device communication.

Why Trezor Bridge Is Important

Without Trezor Bridge, most web-based crypto services cannot detect or interact with your Trezor device. Installing Trezor Bridge ensures:

• Secure browser-to-device communication
• Compatibility with supported web wallets
• Protection against malicious browser access
• Stable and reliable Trezor detection

It is a critical component for users who prefer browser-based crypto management.

How Trezor Bridge Works

1. You connect your Trezor hardware wallet to your computer
2. Trezor Bridge runs quietly in the background
3. A supported web application requests access
4. Trezor Bridge verifies and forwards the request
5. You confirm all actions directly on your Trezor device

Every transaction or login must still be approved on the hardware wallet itself.

When Do You Need Trezor Bridge?

You need Trezor Bridge if you:

• Use Trezor with browser-based wallets
• Access crypto services through web interfaces
• Log in to supported exchanges with Trezor
• Manage assets via third-party web apps

If you only use Trezor Suite desktop, Trezor Bridge is usually not required, as Suite has built-in communication support.
