At a glance — what changed and why it matters
Trezor Bridge was a small background helper that enabled web browsers and apps to communicate with the physical Trezor device over USB. As platform requirements evolve, the recommended user flow has shifted toward using Trezor Suite — the official desktop application that centralizes device setup, firmware updates, and coin management.
Why use Trezor Suite instead of legacy Bridge?
- Simplified connectivity: Suite bundles the recommended connectivity stack so you have fewer moving parts.
- Automatic updates: Suite checks for updated firmware and tools and reduces compatibility surprises.
- Security-first UX: Clear prompts, device-only confirmations, and fewer manual approvals.
Safe download & verification
Always download from official Trezor endpoints: trezor.io/start or the official Suite page. If the release includes PGP signatures or file hashes, verify them before running an installer. Avoid third-party mirrors or "download aggregators" — these are the most common source of supply-chain risks.
Install & connect — concise steps
- Get the right package: select the Suite installer for your OS, or the Bridge package only if explicitly needed by your workflow.
- Verify signature/hashes: optional but recommended — compare signatures where available.
- Run installer and launch: accept the normal permissions; on some OSes you will be prompted for administrator rights.
- Plug in your Trezor: confirm the device screen shows the expected welcome or prompt; never enter your seed anywhere.
- Follow on-screen prompts: approve actions directly on the Trezor device when asked.
Troubleshooting — quick wins
If a device is not detected, try these proven fixes:
- Swap the USB cable — use a data-capable cable (not power-only).
- Use a different USB port or a direct motherboard port (avoid hubs initially).
- Uninstall older Bridge versions that may conflict, reboot, then reinstall Suite.
- Update your OS and browser to the latest stable versions.
- Check device firmware and update only if the vendor’s official guidance recommends it.
Security musts — short checklist
- Never share your recovery seed — Trezor will never ask for it.
- Verify download fingerprints and use official domains only.
- Confirm every transaction on the device screen (not in the app alone).
- Prefer hardware-protected 2FA and keep the host machine updated.
When to remove legacy Bridge
If you’ve migrated successfully to Trezor Suite and no apps require standalone Bridge, uninstall Bridge following the official uninstall guide. Keeping unused helpers increases your system’s attack surface and may cause unexpected conflicts.
Additional notes for advanced users
Developers and power users who script installations or maintain offline images should mirror the official artifacts (signed binaries) and re-check signatures periodically. For offline or isolated environments, consult Trezor documentation for recommended verification steps and reproducible artifact references.
