What is Trezor Bridge?

Trezor Bridge is a lightweight, local software bridge that allows web browsers and web-based wallets to communicate with your Trezor hardware wallet. Trezor Bridge creates a secure, local channel so that the browser can safely request signing, firmware updates, and account information while your private keys remain on the Trezor device. If you want to connect your Trezor to web browsers, download and install Trezor Bridge for a trusted, fast, and secure connection.

Why use Trezor Bridge?

• Secure browser connection: Trezor Bridge enables web wallets and browser apps to communicate with your device without exposing private keys.
• Cross-platform: Available for Windows, macOS, and Linux — Trezor Bridge runs locally and integrates with major browsers.
• Firmware & updates: Trezor Bridge supports official firmware installations and device maintenance through trusted web flows.
• Reliable UX: When Bridge is installed, web applications detect your device quickly, making the experience fast and user friendly.

Quick setup — install Trezor Bridge in minutes

1. 1

   Download the installer

   Get the official Trezor Bridge installer from the trusted Trezor website. Always verify you are on the official domain before downloading.

2. 2

   Run the installer

   Run the downloaded installer for your operating system and follow prompts. On some systems you may be asked to allow local network access — grant permission so browsers can communicate with Bridge locally.

3. 3

   Connect your Trezor

   Plug in your Trezor device, open your browser, and visit a supported web wallet or Trezor web interface. The browser will detect Bridge and request permission to connect to your device.

4. 4

   Approve on device

   Approve connection and actions directly on your Trezor hardware device. Signing requests and firmware operations always require physical confirmation on the device for security.

Best practices and security tips

Use these best practices when you install and use Trezor Bridge to keep your crypto secure:

• Always download Trezor Bridge from the official Trezor domain and verify the source.
• Never enter your recovery seed into a computer or browser — recovery phrases must be recorded offline.
• Approve actions only on the physical device; never accept unexpected signing requests from the browser.
• Keep Trezor Bridge, your browser, and device firmware updated to the latest official releases for performance and security.

Troubleshooting common Bridge issues

If your browser does not detect the Trezor device after installing Bridge, try these quick fixes:

• Restart your browser and, if necessary, your computer.
• Ensure Bridge is running in the background (check system tray / menubar).
• Try a different USB cable or USB port — some cables are power-only and do not transfer data.
• Temporarily disable browser extensions that could interfere with device detection.
