Trezor Bridge: Connect Your Hardware Wallet Seamlessly

Trezor Bridge is the lightweight communication service that allows your browser and operating system to talk directly to your Trezor hardware wallet. Without it, many browsers can’t reliably detect or interact with the device. Installing Trezor Bridge makes setup smoother, transactions more dependable, and firmware or app updates straightforward—all while keeping your private keys offline and protected on the hardware wallet.

What Trezor Bridge Does

The Bridge runs quietly in the background and exposes a secure local connection so Trezor Suite (desktop or web) can discover your device, request confirmations, and manage supported coins. It replaces older browser plugins and reduces compatibility headaches by standardizing how your computer communicates with the wallet. Because sensitive operations occur on the device itself, the Bridge never sees or stores your seed, PIN, or passphrase.

How to Install Trezor Bridge

Installation is quick and beginner-friendly:

• Visit the official Trezor site and download the Bridge installer for your operating system (Windows, macOS, or Linux).
• Close your browser before running the installer to ensure the service registers properly.
• Launch the installer and follow the prompts. Administrator permission may be required.
• After installation, reopen your browser or start Trezor Suite. Plug in your Trezor device using a known-good USB cable.
• If prompted by your OS, allow the service to run at startup so future connections work instantly.

Once installed, Trezor Suite should detect your device automatically. If it doesn’t, see the troubleshooting section below.

Using Trezor Bridge with Trezor Suite

Trezor Suite is the control center for balances, sending and receiving, coin accounts, and security settings. With the Bridge installed:

• Device discovery: Suite will recognize your Trezor and prompt you to unlock it with your PIN.
• Transaction approval: Every critical action must be confirmed on the device screen, protecting you from malware.
• Firmware & coin support: Bridge helps Suite perform updates cleanly and install the latest coin features.
• Advanced protection: Use a passphrase (optional) for an extra layer of security, entered directly on-device when supported.

Troubleshooting & Best Practices

If your device isn’t recognized, work through these quick checks:

• Verify Bridge is running: Reopen Trezor Suite or restart your computer to reload system services.
• USB cable & port: Try a different cable and a direct motherboard port. Avoid unpowered hubs.
• Browser conflicts: Close extra tabs that may be using WebUSB/WebHID, and ensure only one Suite instance is active.
• Permissions: On macOS and Linux, confirm you granted necessary permissions during install.
• Security software: Temporarily whitelist the Bridge and Suite if an antivirus is blocking local connections.

For consistent performance, keep Trezor Suite updated, confirm the device’s hologram/seal when unboxed, and always verify transaction details on the hardware screen before approving.
