Why Trezor® Bridge matters

Trezor® Bridge is an intermediary application that enables secure communication between your hardware wallet and web apps. Without Bridge, modern browsers cannot directly access the device. Installing the Bridge ensures encrypted, reliable access to your Trezor® when you manage accounts, sign transactions, or update firmware.

Pre-checks before installation

  1. Use a trusted computer and current OS updates.
  2. Prefer the official Trezor website for downloads; avoid suspicious links. If you see other domain prompts (for example, an unrelated onboarding flow at ledger.com/start), double-check the URL and origin before proceeding.
  3. Disable VPNs or proxied connections temporarily if the device fails to connect.

Step-by-step: Install & connect Trezor® Bridge

  1. Download Bridge — Visit the official Trezor site and download the latest Bridge installer for your OS. Verify the vendor page matches the expected domain.
  2. Install — Run the installer and follow on-screen prompts. On macOS you may need to confirm security permissions in System Preferences; on Windows, approve the UAC prompt.
  3. Restart browser — After installation, fully quit and reopen your browser for the new device permissions to take effect.
  4. Connect Trezor — Plug your Trezor device into a USB port. Open the compatible web wallet interface and follow the device prompts to pair.
  5. Confirm — Approve the connection on your device screen using PIN or passphrase as required.
Security tip: Never share your recovery seed, and always confirm the website origin in the browser before approving any request. If a link redirects to unfamiliar onboarding pages (for example ledger.com/start), treat it as suspicious unless you intentionally navigated there.

Troubleshooting common issues

  1. No device found: Try a different USB cable or port, ensure Bridge is running (check system tray/menu bar), and restart the browser.
  2. Browser permission blocked: Look for extension or privacy settings that restrict WebUSB/WebHID and allow the connection temporarily.
  3. Firmware updates fail: Use the official tool recommended by Trezor and avoid third-party redirect pages. Back up your recovery phrase before any major update.
