Trezor Bridge — official connection & migration guide

Connect your Trezor device safely — Bridge, Suite & current best practice

Short answer: follow official guidance. Trezor historically used Bridge as a helper to connect hardware wallets to web apps; in recent guidance the standalone Bridge has been deprecated in favor of Trezor Suite workflows. This guide covers downloads, compatibility, secure installation, migration steps, and troubleshooting.

Overview — what Trezor Bridge did and what changed

Trezor Bridge was a lightweight background helper that allowed browsers and desktop apps to communicate securely with Trezor hardware wallets. It handled USB connectivity and negotiated communication between the device and Trezor Suite or compatible web apps. Recently, Trezor announced the deprecation/removal of the standalone Bridge and recommends following the Trezor Suite flow for the smoothest, most supported experience. This affects users who still rely on older Bridge installers — uninstall guidance and migration steps are available from the official pages.

Where to download (and verify) safely

Always download Bridge, Trezor Suite, or any Trezor tool from official domains: trezor.io/start or the official Trezor Suite pages. When installers provide PGP signatures or fingerprints, verify them before running the installer. Do not use third-party sites to fetch Bridge executables; unofficial builds may be tampered with.

Compatibility & platform notes

Historically Bridge provided installers for Windows (EXE with optional PGP signature), macOS, and Linux (DEB/RPM). If you need the Bridge packages directly for scripting or offline installs, official download hosts maintain these artifacts — but because guidance and supported flows evolve, check the official download endpoints first before proceeding.

Migration: why Trezor Suite is the recommended path

Trezor Suite is the official application that consolidates wallet management, swaps, and device setup. It provides a guided, secure environment that reduces the need for standalone Bridge in many scenarios. If you are moving from a legacy setup, install Trezor Suite, connect your device, and follow the Suite's prompts to migrate workflows — Suite includes the current recommended connectivity stack and reduces compatibility friction with modern browsers and OS updates.

Step-by-step: safe install & connect (concise)

  1. Visit the official start page: trezor.io/start.
  2. Download the Trezor Suite (or Bridge installer only if explicitly required).
  3. Verify signatures when available and run the installer as an administrator / with appropriate privileges.
  4. Connect your Trezor device and confirm device prompts — never reveal your recovery seed during this process.
  5. Use Trezor Suite or official web apps; if you see unexpected prompts or unrecognized apps, disconnect and consult support.

Troubleshooting common issues

Device not detected: try a different USB cable/port, uninstall any old Bridge versions, reboot, and ensure the device screen shows the correct prompt. Browser problems: avoid using outdated browser builds; prefer latest stable Chrome, Edge, or Firefox versions and follow official app guidance. If you previously installed a standalone Bridge and experience conflicts, follow official uninstall instructions before installing Suite.

Security & best practices (must-follow)

  • Only use official Trezor downloads and verify digital signatures where provided.
  • Never share your recovery seed — Trezor will never ask for it.
  • Use hardware 2FA and a secure host machine (keep OS and browser updated).
  • Whitelist withdrawals and check transaction details on the device screen before approving.
