How to Install & Use Trezor Bridge (2025 Guide)

If you use a hardware wallet from Trezor (like Trezor One or Trezor Model T) and want to manage your crypto through a browser or web wallet, then Trezor Bridge is a key component. This guide explains what Trezor Bridge does, why it’s essential, and exactly how to download and install it safely on your computer.

What Is Trezor Bridge — and Why You Might Need It

Trezor Bridge is the official software that acts as a secure communication bridge between your Trezor hardware wallet and web-based or desktop wallet interfaces (like Trezor Suite or other compatible wallets). It’s a small background service that enables your browser to safely interact with the hardware wallet over USB, without exposing private keys or sensitive data. Trezr Bridge Docs+2Bridge Tzorfaq+2

Key benefits:

  • Allows browser‑ or web‑based wallets to detect your Trezor device reliably (since browsers block direct raw USB access by default). Trezor Help Center+1

  • Ensures secure, encrypted communication between your computer and your hardware wallet while keeping private keys offline on the hardware device. Trezr Bridge Docs+1

  • Works across major operating systems — Windows, macOS, and many Linux distributions. Trezor Bridge+1

Because of this, if you plan to manage crypto via browser wallets or web versions of Trezor tools — rather than through purely offline interactions — Trezor Bridge is generally required. Trezor Help Center+1

How to Download & Install Trezor Bridge (Step by Step)

Here’s a clear walkthrough to download and install Trezor Bridge correctly:

1. Go to the official download page

Visit the official Trezor site: trezor.io/bridge. This is the only safe source — avoid third‑party websites or mirrors. Trezr Bridge Docs+2Help Bridge+2

2. Choose your operating system

Trezor Bridge offers installers for:

  • Windows (installer .exe)

  • macOS (dmg or package)

  • Linux (AppImage, .deb/.rpm packages or distribution packages depending on distro) Trezor Bridge+1

3. Run the installer and grant permissions

  • Windows: Run the downloaded .exe, approve any prompts (you may need admin privileges). Bridge Tzorfaq+1

  • macOS: Open the .dmg or .pkg, drag to Applications if needed. On first run you may have to allow USB or security permissions depending on your macOS version. Trezer Bridge Guide+1

  • Linux: Use the provided package for your distribution (e.g. .deb for Debian/Ubuntu) or the AppImage. Sometimes you may need to set up additional USB permissions (udev rules) so non-root users can access USB devices. Trezor Bridge+1

4. Restart your browser (if prompted)

After installation, it's a good idea to restart your browser to ensure Bridge is recognized. Help Bridge+1

5. Plug in your Trezor hardware wallet

Connect your device via USB. Bridge should detect it, and your web wallet or Trezor Suite web interface should prompt to connect. Unlock the device (enter PIN) and confirm device prompts to allow access. Trezor Help Center+1

6. Begin managing your crypto via web‑wallet or Trezor Suite

Once Bridge is running and your device is connected, you can add accounts, send/receive crypto, manage assets — while your private keys remain safely on the hardware wallet.
