What is Trezor Bridge?

Trezor Bridge is a lightweight local application that enables communication between your browser and your Trezor Hardware Wallet. It is required when accessing the Trezor Wallet web interface or using the Trezor Suite App on desktops that rely on browser-based connectivity.

Why you need it

While modern browsers block direct USB access for security reasons, Trezor Bridge creates a safe, local channel so you can sign transactions, manage accounts, and access advanced wallet features without exposing your recovery seed. Think of it as the secure translator between your device and your software.

Quick links

Using Trezor Wallet & Trezor Suite

Open the Trezor Wallet or launch the Trezor Suite App. If your browser prompts you, allow the Trezor Bridge connection. To access account features, visit the Trezor Wallet Login flow or use Trezor Login via the Suite. The application will guide you through device pairing and PIN entry — your private keys never leave the device.

Safety tips

  • Download Bridge and Suite only from trezor.io.
  • Never share your recovery seed — Trezor will never ask for it online.
  • Keep software up to date: check for the latest Trezor Bridge Download and Trezor Suite Download releases regularly.

Need help?

If you have trouble connecting, restart the Bridge, try a different USB cable or port, and consult the setup wizard at trezor.io/start. For step-by-step support, Trezor’s documentation and community pages provide screenshots and troubleshooting guides.

Privacy-first design

Trezor products prioritize decentralization and privacy. Whether you use the web-based Trezor Wallet or the full Trezor Suite, the Bridge keeps interactions local: transactions are prepared on your device and signatures are produced inside the hardware wallet itself, ensuring maximum protection against remote attacks.

For mobile, consider pairing solutions supported by the Suite — the Trezor Suite App provides a unified experience across devices.
