Trezor Bridge — How to Download, Install & Use Trezor Bridge
A friendly, step-by-step Trezor Bridge setup and troubleshooting guide to connect your Trezor device securely.
Trezor Bridge is the official small background app that enables secure communication between your Trezor hardware wallet and your browser (or desktop wallet apps). This guide explains what Trezor Bridge does, how to download and install it, common connection issues and how to keep Trezor Bridge secure.
Trezor Bridge — Why you need it
Trezor Bridge acts as the translator between your Trezor device and web or desktop wallet interfaces (like Trezor Suite and compatible web wallets). Without a properly installed Trezor Bridge, your browser cannot detect or communicate with the Trezor hardware.

Always download Trezor Bridge from the official Trezor channels to avoid malicious copies. Official links:
Trezor Bridge — How to install (Windows, macOS, Linux)
- Download the installer for your operating system from the official Trezor page above.
- Run the installer and follow on-screen prompts. Allow the installer to run system drivers if prompted (Windows).
- Restart your browser after installation and reconnect your Trezor device to the USB port.
- Open the official Trezor Suite web app or desktop app and complete the initial device handshake when prompted.
Tip: On macOS, you may need to allow the Bridge app in System Settings → Security & Privacy if macOS flags it the first time.
Trezor Bridge — Connecting your device
After installing Trezor Bridge:
- Use a known-good USB cable (data+power capable) and a direct USB port on your computer — avoid USB hubs for the first setup.
- Unlock your Trezor device with your PIN when prompted on the device screen.
- Authorize the connection on the device when the browser or Trezor Suite requests permission.
Trezor Bridge — Common issues & fixes
Browser doesn't detect Trezor: Ensure Trezor Bridge is running (check system tray / activity monitor). Restart browser after installing Bridge.
Permission denied / blocked: Accept or allow the USB permission prompt in your browser. Try disabling strict privacy extensions temporarily.
Driver errors (Windows): Reinstall Trezor Bridge as administrator and try a different USB port or cable.
Important: If anything asks for your recovery seed or private key during setup, close everything and verify you are on the official site. Trezor devices never ask for your seed through the browser.
Trezor Bridge — Security best practices
Keep your Trezor Bridge environment secure by following these rules:
- Only download Trezor Bridge from trezor.io.
- Keep your OS and browser up to date to reduce exposure to vulnerabilities that could interfere with Trezor Bridge.
- Use antivirus/malware scanning on downloaded files and verify checksums when provided by official sources.
- Never share your recovery seed, and never enter it into a computer or website. Your seed belongs only on paper (or metal backup) and inside your head.
Trezor Bridge — Troubleshooting checklist
- Confirm Trezor Bridge is installed and running.
- Try a different USB cable and port; avoid front-panel hubs.
- Restart your browser and/or computer.
- Disable browser extensions that may block USB access (privacy blockers, aggressive security extensions).
- Reinstall Trezor Bridge from the official site if problems persist.
