Trezor Bridge — Install & Connect

Trezor Bridge is the small USB-to-browser helper that lets your computer and Trezor device communicate securely with Trezor Suite and compatible web apps.

What is Trezor Bridge?

Trezor Bridge is a native background application that creates a secure local connection between your Trezor device and your browser or Trezor Suite. It replaces legacy browser plugins and improves compatibility across operating systems.

Use the official download page: trezor.io/bridge.

Download & Install — Quick Steps

1

Get the Bridge

Visit trezor.io/bridge and choose the installer for your OS (Windows, macOS, Linux).

2

Run the Installer

Open the downloaded file and follow on-screen instructions. You may need administrator privileges. Accept any prompts to install the service/driver.

3

Connect Your Device

Plug in your Trezor using the included USB cable. Open suite.trezor.io or the Trezor Suite app — the Bridge runs in the background and will be detected automatically.

4

Verify Communication

Your browser should prompt to allow connection. Verify the address shown on your Trezor device for any transaction or sensitive action.

Verifying the Download

Always download Bridge from the official site. If Trezor provides checksums or signatures, verify them to ensure file integrity. Never install Bridge from third-party mirrors or untrusted sources.

Pro tip: If a website link was sent over email, type trezor.io/bridge manually into your browser to avoid phishing.

Troubleshooting

  • Bridge not detected? Restart your computer and reconnect the device.
  • Windows users: try a different USB port (avoid USB hubs). Check Device Manager for driver issues.
  • macOS: ensure macOS security settings allow the installer (System Settings → Privacy & Security).
  • Linux: follow distro-specific instructions — you may need to add udev rules (see official docs).
  • If your browser still can't access the device, try closing/reopening the browser or reinstalling Bridge.

If problems persist, consult the official support pages at trezor.io/support.

Security & Best Practices

  • Download only from trezor.io.
  • Keep Bridge updated; updates may include security fixes and compatibility improvements.
  • Verify firmware and transit signatures via official Trezor channels when prompted.
  • Never enter your recovery seed into any app — seeds must remain offline.
  • Use strong OS account passwords and keep your system patched.

Advanced — Running Bridge Manually (Linux)

On some Linux systems you may want to run Bridge manually or inspect logs. Typical commands (example):

# install (example)
sudo apt install trezor-bridge

# check status
systemctl --user status trezord

Refer to official Linux installation docs for exact package names and udev rules.
