What is Trezor Bridge?

Trezor Bridge is a crucial communication tool that enables secure interaction between your web browser and Trezor® hardware wallet. This background service acts as a secure bridge, facilitating the Trezor Bridge Login process when using the web version of Trezor Suite.

Unlike the desktop Trezor Suite app which has built-in communication capabilities, the web interface requires Trezor Bridge to establish a secure channel between your browser and hardware device. This ensures that sensitive operations during the Trezor login process remain protected from browser-based vulnerabilities.

Security Note: Trezor Bridge creates an isolated communication channel, preventing browser extensions and malicious websites from intercepting data between your device and Trezor Suite.

How Trezor Bridge Works

🌐

Browser Request

When you access the web version of Trezor Suite, your browser sends a connection request to your Trezor® device.

🌉

Bridge Activation

Trezor Bridge intercepts the request and establishes a secure local connection with your hardware wallet.

🔐

Secure Channel

The bridge creates an encrypted tunnel for data transmission, enabling the Trezor Bridge Login process.

Authentication

You complete the Trezor login on your device, with all communication protected by the bridge.
