What is Trezor Bridge and why you need it
Trezor Bridge is a small background service (Windows, macOS, Linux) that bridges USB communication between your Trezor® device and web-based tools or the Trezor Suite. Without it, browsers may not reliably detect the hardware wallet for a successful Trezor Wallet Login or when initiating transactions.
Download & Installation (step-by-step)
- Go to the official Trezor Bridge page.
- Choose the installer matching your OS (Windows / macOS / Linux) and download the signed package.
- Run the installer and follow prompts — admin privileges may be required on some systems.
- Restart your browser if it was open during installation, then connect your Trezor® device.
- Visit trezor.io/start or open Trezor Suite to begin device setup and login flow.
Security & Best Practices
- Only download Bridge from trezor.io to avoid phishing installers.
- Keep Bridge and Trezor Suite updated — updates include security fixes and compatibility improvements.
- Use official Trezor® Hardware Wallet firmware and verify device authenticity when unboxing.
- Never share your recovery seed; Bridge does not access or transmit seeds, it only enables device communication.
Troubleshooting common Bridge issues
If the browser or Suite fails to detect your device: ensure the USB cable is data-capable (not charge-only), reinstall Bridge, try a different USB port, reboot your computer, and ensure browser permissions allow USB access. For persistent problems see the official support at trezor.io/start.
FAQ
Does Trezor Bridge expose my recovery seed? No — Bridge only facilitates USB communication; all private keys and seeds remain on the Trezor® device.
Is Bridge required for Trezor Suite Desktop? On many systems, Suite communicates directly; Bridge is recommended for browser integrations and older OS/browser combinations.
Where to download Trezor Suite? Get the official Suite at suite.trezor.io or follow instructions on trezor.io/start.
