Trezor Bridge — Connect Trezor to Trezor Suite Securely (H1)

A clean, secure conduit that lets your hardware wallet and suite talk without exposing keys.
Secure & Local

Trezor Bridge is a small background connector that enables safe, local communication between your physical Trezor device and the Trezor Suite desktop application. It never sends private keys over the internet and acts only as a transport layer for encrypted commands and responses.

Why it matters: modern hardware wallets intentionally separate private key storage from the internet. The bridge allows your browser or desktop app to detect and talk to the device without opening a network-facing API. When installed correctly and kept up to date, it reduces friction and keeps interactions predictable and auditable.

Fresh theme & layout notes

This page uses a light ocean-inspired theme with teal-blue accents and generous white space to communicate clarity and trust. The layout places the how-to and security guidance at the center, with quick actions and support on the right. Typography is slightly condensed for dense technical content while remaining legible on phone screens.

Quick setup (overview)

  1. Download the official Trezor Bridge from the vendor site (verify the domain and checksum).
  2. Install and allow the background service (macOS/Windows/Linux prompts may appear).
  3. Open Trezor Suite — the suite will auto-detect the installed bridge and your device when plugged in.
  4. Follow the on-device PIN and passphrase prompts; never enter seed words into your computer.

Security reminders

Only install Bridge from official sources. Keep Bridge and Suite updated. Use the device's screen to confirm every transaction, check addresses visually, and enable firmware verification. If you suspect tampering, disconnect immediately and verify firmware via Trezor Suite's verify flow.

Frequently Asked Questions

1. Is Trezor Bridge safe to run in the background?
Yes — Bridge only listens locally (127.0.0.1) and requires user approval to forward commands. It is designed to minimize attack surface compared to enabling browser USB APIs directly.
2. Can Bridge access my seed or PIN?
No — Bridge is a transport. Your seed and PIN live in the Trezor device and are never exposed to the host computer or the bridge process.
3. What if my computer doesn't detect the device?
Try reconnecting the USB cable, use a known-good cable, restart Bridge (or the computer), or check firewall/antivirus settings that might block localhost services.
4. Do I need Bridge for mobile?
Trezor Bridge is primarily a desktop connector. Mobile devices typically use Bluetooth or platform-specific connectors; consult Trezor Suite mobile docs for details.
5. How do I verify Bridge integrity?
Verify checksums from the official site, and cross-check with vendor-signed releases. If in doubt, contact official support using the channels below.
