About Trezor Bridge

Trezor Bridge® is the official communication layer that securely links your Trezor hardware wallet to supported web interfaces and applications. It runs locally on your machine, mediating USB/WebUSB/WebHID requests while ensuring your private keys never leave the device.

Bridge is used primarily with browser-based versions of Trezor Suite or other third‑party dApps that require a secure handshake. In modern browsers with native WebUSB support, Bridge may not always be required—but it's still fundamental for broader compatibility.

Sign In: How It Works

Note: There is no “Bridge login” in the traditional sense. The sign-in happens via your hardware device (PIN entry, device confirmation) through a web or suite interface. Bridge simply enables the connection layer.
  1. Install Trezor Bridge (if required) on your computer.
  2. Open suite.trezor.io or another trusted web interface or desktop application.
  3. Connect your Trezor device via USB.
  4. The interface will detect Bridge (or native WebUSB) and request a connection.
  5. On your device, enter your PIN (or confirm passphrase) as prompted.
  6. Once confirmed, the interface logs you in and you gain access to your wallet functions.

Always confirm the addresses, transaction details, and origin domain that appear on your Trezor device’s screen to guard against phishing.

Sign In to Your Account*

This “sign in” form is purely illustrative. The actual secure login process is mediated via your Trezor device and the web interface you’re using (Suite, web wallet, etc.).

Installation & Setup Guide

  1. Go to the official Trezor download page and choose Bridge for your OS.
  2. Run the installer; accept required permissions.
  3. After installation, Bridge runs in the background (tray/menu bar icon).
  4. Restart browser or web app to detect Bridge.
  5. Connect Trezor and authorize the web interface to interact.

If you already use a modern browser that supports WebUSB natively, the Bridge download may not be necessary. But if the web wallet prompts you, always use the official source.

Security & Best Practices

Private Keys Stay on Device

Bridge never handles or stores your private keys or seed phrase. All signing and decryption operations happen on the hardware wallet itself.

Origin & Permission Checks

Bridge enforces strict checks so only authorized web origins (domains) can access your device. You’ll see domain prompts and must confirm actions on the device itself.

Verify Downloads

Only download Bridge from the trusted Trezor site (e.g. trezor.io/start). Validate signatures or checksums if provided to avoid malicious copies.

Always cross-check the transaction details displayed on your Trezor device before approving. Phishing sites may try to trick you by showing manipulated UI—but the device screen is your last line of truth.

Troubleshooting & Common Issues

Bridge Not Detected

Ensure the Bridge service is running (look in system tray / menu bar). Restart it or reinstall if necessary.

Browser Doesn’t Detect Device

Try a different USB port or cable. Disable extensions (adblockers, privacy tools). Restart both browser and device.

Conflicts with Legacy Bridge Versions

Uninstall older Bridge apps before installing new ones to avoid port conflicts or duplicate services.

Native WebUSB vs Bridge Confusion

Some modern browsers no longer require Bridge if they support WebUSB. If a wallet says “install Bridge,” verify whether your browser truly needs it or if it's a prompt based on compatibility heuristics.

Frequently Asked Questions

Is there a “Bridge account login”?

No — Bridge is not an account or wallet interface. It’s a background service facilitating secure connections. The actual login is done via your hardware device and wallet UI.

Do I always need Bridge?

Not always. On modern browsers supporting WebUSB, Bridge may be optional. But many wallets or setups still rely on Bridge for compatibility.

What if I enter the wrong passphrase?

Your passphrase is part of the hidden wallet derivation. Entering it incorrectly may lead to an empty wallet; you’ll need to re-enter or clear and retry.

Can Bridge access my seed phrase?

No. Bridge only handles message passing. It never holds or transmits secret seed phrases, private keys, or PINs.

Is Bridge safe to run constantly?

Yes — it is lightweight and designed to run silently. If you prefer, you can start/stop it as needed. Just ensure it’s running when you try to connect your wallet.

Your Next Steps

1. Download and install Trezor Bridge from a trusted source. 2. Restart browser/app and connect your Trezor hardware. 3. Open suite.trezor.io (or your wallet UI) and authorize the device. 4. Log in via PIN and approve any actions directly on your device. 5. Always keep firmware, Bridge, and your browser updated to the latest versions for security.

With these steps, you'll have a secure, reliable connection between your hardware wallet and your crypto interface — keeping your assets safe while giving you seamless access.
