Trezor Bridge — what it was, why it’s deprecated, and migration guidance

About Trezor Bridge

Trezor Bridge was a small helper application that allowed browsers and certain apps to communicate with Trezor hardware wallets over USB. As of recent product updates the standalone Bridge application has been deprecated and users are advised to uninstall it and use the supported alternatives described below.

Key points (short)

  • Standalone Trezor Bridge is deprecated and may be removed by future releases.
  • Installations of the standalone Bridge can interfere with the Trezor Suite app or browser integrations — consider uninstalling it.
  • Use Trezor Suite (desktop or web) for the recommended, secure experience.

Why it was deprecated

Trezor's software ecosystem has evolved: the Trezor Suite app and modern browser APIs provide secure, integrated device connectivity without requiring a separate background service for most users. Deprecating the standalone Bridge simplifies maintenance and reduces potential conflicts and attack surface.

What you should do now

  1. Check if Bridge is installed: On Windows/Mac/Linux check your installed apps ("Add or remove programs" on Windows; Applications on macOS; package manager or /usr/bin on Linux).
  2. Uninstall Bridge: If installed, follow your OS uninstall flow. On Windows use Settings → Apps; on macOS drag the Bridge app to Trash or use an uninstaller if present.
  3. Use Trezor Suite: Download the latest Trezor Suite desktop app or use the web app at trezor.io/trezor-suite. The Suite manages device connectivity and firmware updates.
  4. Keep software up to date: Ensure Trezor Suite and your device firmware are current to avoid compatibility issues.
Note: If you rely on a specific third-party web wallet that still requires Bridge, check that wallet’s documentation — many have migrated to alternative connection methods or updated instructions.

Uninstall — quick commands

Common quick references (examples). Use only the command that matches your OS and comfort level.

Windows (PowerShell): Get-WmiObject -Class Win32_Product | Where-Object {$_.Name -like "Trezor Bridge*"} | ForEach-Object { $_.Uninstall() }
macOS (if installed as app): rm -rf /Applications/Trezor\ Bridge.app
Linux (Debian/Ubuntu): sudo apt remove trezor-bridge

If you’re uncomfortable using command-line removal, use your OS graphical uninstaller instead.

Troubleshooting

  • Device not recognized: after uninstalling Bridge, reboot and try connecting with Trezor Suite. Try different USB ports/cables.
  • Browser integration issues: use the Trezor Suite desktop app or the official web app; avoid unofficial third-party Bridge installers.
  • Firmware/update prompts: accept firmware updates only inside the official Trezor Suite app.

Security & best practices

  • Download Trezor software only from trezor.io to avoid malicious installers.
  • Do not install Bridge copies from unknown sites — many outdated mirrors or unofficial pages exist.
  • Always verify checksums/signatures if provided for any installers you download.
