Trezor Bridge® is an essential background service that allows your Trezor hardware wallet to communicate securely with modern web browsers. If you use Trezor Suite or web-based wallet interfaces, Trezor Bridge ensures that your device can be detected, verified, and used smoothly without complicated manual configuration. This guide explains what Trezor Bridge is, how it works, how to install it, and how to use it safely when connecting your Trezor to the web.

Trezor Bridge® is a lightweight communication layer developed by SatoshiLabs. It runs silently in the background on your computer and acts as a secure bridge between your Trezor device and your browser. Without it, web applications would not be able to detect your device reliably due to modern browser security restrictions.
Instead of allowing direct low-level hardware access from websites, Trezor Bridge provides a controlled, verified channel that keeps your private keys isolated within the hardware wallet. This design dramatically reduces attack surfaces while preserving ease of use.

Web browsers continue to increase their security restrictions to protect users from malicious scripts and unauthorized device access. While this is excellent for general security, it can complicate legitimate hardware wallet connections. Trezor Bridge solves this problem by serving as a trusted intermediary.
With Trezor Bridge installed, supported websites and Trezor Suite can communicate seamlessly with your device. You simply plug in your wallet, open your preferred interface, and confirm actions on the device screen.

Trezor Bridge runs as a small background service. When you connect your Trezor device via USB, the Bridge recognizes it and opens a local communication port. Your browser-based wallet interface sends requests to this local service instead of directly to the device.
Trezor Bridge verifies that requests come from supported interfaces and then forwards them securely to your Trezor. The device itself always requires physical confirmation for sensitive actions such as sending transactions or exporting public keys.
The Bridge acts like a translator between the USB-connected wallet and browser software. It ensures messages are formatted correctly, signed, and delivered only to authorized processes. Private keys never leave the device; Trezor Bridge only transports encrypted commands and responses.
Every operation must be approved on your Trezor’s screen. This ensures that even if a browser is compromised, it cannot silently move funds. The Bridge itself does not store sensitive data; it merely facilitates secure communication.

After installation, no additional configuration is typically required. Trezor Bridge updates can be installed when new security improvements become available.
If you are using a managed or restricted computer, administrator privileges may be required to install the Bridge. Always consult your system administrator if installation is blocked.
Once installed, Trezor Bridge works silently. When you open Trezor Suite Web or a supported third-party wallet, the site automatically checks for the Bridge service. If found, your Trezor device becomes accessible.
Trezor Bridge supports modern versions of Chrome, Firefox, Edge, and other Chromium-based browsers. It eliminates the need for deprecated plugins and ensures stable, forward-compatible connectivity.

Trezor devices are designed so that even if malware infects your computer, it cannot approve transactions on your behalf. The Bridge only transmits messages; the device always requires button confirmation.
If your browser does not detect your Trezor, the issue is often related to permissions, outdated software, or USB connectivity. Most problems can be resolved quickly.
