Trezor Bridge — Install & Connect Your Trezor® Wallet Securely

A practical, security-first walkthrough for installing Bridge (or using Trezor Suite) and connecting your hardware wallet safely to desktop apps and browsers.

Why this matters

A hardware wallet like Trezor keeps your private keys offline, but your computer still needs a secure way to talk to the device. Historically this was handled by a small background utility called Trezor Bridge. Today, Trezor’s official apps (Trezor Suite) often include the needed connectivity — and the project has moved toward integrating Bridge functionality inside the Suite for a smoother, safer experience.

Quick note: If you already use Trezor Suite, you may not need a separate Bridge install. Always prefer official downloads from the Trezor site and keep software updated.

Before you start — preparation & safety

Checklist

Use a trusted machine: avoid public or untrusted computers.
Back up your recovery seed before making changes; never store it digitally.
Download installers only from the official Trezor website or verified app stores.
Temporarily close other wallet/browser extensions that might interfere.

Recommended OS & app

Trezor supports Windows, macOS, and major Linux distributions. For the best experience, install the latest Trezor Suite desktop app (it provides device connectivity, portfolio features, and built-in security checks). If your workflow still requires a standalone Bridge, follow the OS-specific guide below.

Step-by-step: Install & connect

1. Download from the official site

Open your browser and go to the official Trezor start page. Choose the desktop app (Trezor Suite) for your OS, or the Bridge installer if specifically required by an application.

2. Install (Windows & macOS)

Run the downloaded installer and follow on-screen prompts.
On macOS, drag the app to /Applications when prompted.
On Windows, allow the installer to run and accept any system prompts for drivers.

3. Install (Linux)

Use the distribution packages or AppImage provided on the Trezor site. For Debian/Ubuntu there may be an APT package; use your package manager to install or remove Bridge if necessary.

4. Connect & open Trezor Suite or your chosen app

Plug your Trezor into a USB port using the official cable.
Open Trezor Suite — the app should detect the device and prompt you to continue.
Follow on-screen instructions on the device itself to confirm actions (every critical action requires manual confirmation on the hardware screen).

If the device isn’t detected: try a different USB port or cable, reboot your computer, or reinstall the official app. Do not download third-party “fixes” from untrusted sites.

Security best practices

Verify downloads

Always download from the official domain. When available, verify signatures or checksums, and prefer the desktop Suite distributed on the official site.

Seed & PIN hygiene

Never enter your recovery seed into a computer or phone. Only write it down on paper (or a metal backup) and store it securely.
Use a strong device PIN and do not reuse it elsewhere.

Software updates

Keep Trezor Suite and your device firmware updated. Updates often include security fixes and improved compatibility. If an app asks you to install firmware, always confirm the update on the device screen before proceeding.

FAQ & troubleshooting

Is Trezor Bridge still required?

Trezor has moved functionality into Trezor Suite in many cases; standalone Bridge may be deprecated in favor of the integrated Suite. If a specific third-party tool asks for Bridge, consult the official documentation for that tool and the Trezor guides.

How do I remove an old Bridge installation?

Follow your OS uninstallation steps (Control Panel / Applications / package manager). If unsure, use official uninstall guides from Trezor support resources.

Where to get help?

Use Trezor’s official guides and support channels. Avoid community mirrors or unofficial downloads for installers.
