Install Trezor Bridge — Step-by-step
1. Download the official installer
Always download Bridge from official Trezor pages to avoid tampered installers. Official links (10 total) are listed in the right column for quick access. Example: https://trezor.io/bridge.
2. Run the installer
Open the downloaded file and follow on-screen instructions. On macOS you may need to allow the application in System Preferences > Security & Privacy > General.
3. Connect your Trezor
Plug your Trezor into your computer and unlock it. The device will show a welcome screen. If prompted, confirm device actions on the Trezor screen itself — never accept prompts from unknown applications.
4. Verify in Trezor Suite or browser app
Open Trezor Suite or a supported web app. The presence of Trezor Bridge lets the website detect your device and complete setup.
Security best practices
Verify official sources
Use the official Trezor domain and pages for downloads and guidance: the list of official links on the right contains direct Treɪzor resources and guides. Avoid third-party installers and always verify the URL before you download.
Protect your recovery seed
Your recovery seed is the single most sensitive secret. Trezor Bridge does not transmit your seed — the device signs transactions locally — but you should always keep your seed offline, on paper, in a secure place.
Keep software updated
Keep Trezor Bridge, Trezor firmware and Trezor Suite up to date to benefit from security fixes and compatibility improvements.
Troubleshooting
Bridge not detecting device
Common fixes:
- Reboot your computer and reconnect the device.
- Try a different USB cable or port (avoid USB hubs).
- Confirm Bridge is running (check system tray / menu bar).
- Reinstall Bridge from the official page.
Browser can't connect
Check browser permissions and ensure no software (VPN, firewall) blocks local connections. Try a different supported browser.
