Trezor Bridge: what it is and why it matters

Trezor Bridge is a small helper application that allows your computer to communicate with your Trezor® Hardware Wallet through the Trezor Suite App or web-based wallet interfaces. It acts as a secure local bridge between USB/USB-C devices and browser apps so you can access Trezor Wallet features like login, transactions, and device management.

Getting started — download & install

Always download Trezor Bridge from official sources such as trezor.io/start or the Trezor Help Center. The typical steps:

  • Visit trezor.io/start and follow the prompts to download Trezor Bridge or the full Trezor Suite Download.
  • Install the Bridge app for Windows, macOS, or Linux and grant any system permission prompts.
  • Open Trezor Suite App (desktop) or the supported browser and connect your Trezor® device via USB.

Trezor login & Wallet access

After Bridge installation, the Trezor Wallet Login flow uses the local bridge to detect your Trezor®. Choose the device, confirm the login on your hardware wallet screen, and approve actions with your PIN or passphrase.

Troubleshooting common issues

If you see "Error Connecting Trezor Account" or "Can't verify Trezor Wallet", try these steps:

  • Restart your computer and reconnect the device.
  • Reinstall the latest Trezor Bridge and update the Trezor Suite App.
  • Try a different USB cable/port — use direct ports, avoid hubs.
  • Disable conflicting browser extensions and ensure browser supports native messaging.
  • Check the Trezor Help Center for platform-specific guidance.

Account recovery, 2FA reset & security

Trezor® never stores your seed. If you face "Unable to login Trezor" due to lost credentials, use your recovery seed with a new device or the Suite's recovery process. For issues around Trezor 2fa reset or device lockouts, consult the official Trezor Help Center — do not share your seed or PIN with anyone.

When to contact support

If you exhaust basic troubleshooting (reinstall Bridge, swap cable/port, update Suite, verify firmware) and still get connectivity or verification errors, open a ticket with the Trezor Help Center. Provide logs, OS version, Bridge version, and concise steps to reproduce.

FAQs

1. What is Trezor Bridge and do I need it?
Bridge is the local connector between your Trezor® device and apps. Use it when your browser or Suite requires native device access.
2. Where can I safely download Trezor Bridge?
Only from trezor.io/start or the official Trezor website. Avoid third-party downloads.
3. Trezor Suite App not working — how to fix?
Update Suite, reinstall Bridge, test another cable/USB port, disable browser extensions, and restart the device.
4. I can’t login — will I lose my funds?
No. Your funds reside on the blockchain. If you cannot login, you can recover your account using your recovery seed on another Trezor® or compatible wallet.
5. How to reset Trezor 2fa or unlock a locked device?
Follow official recovery procedures in the Trezor Help Center. Never share seed or PIN — Trezor support will never ask for them.
6. My browser shows “Can't verify Trezor Wallet” — why?
Often caused by outdated Bridge, blocked native messaging, or a browser extension. Reinstall Bridge and try the Trezor Suite App instead.
