Trezor® Bridge — Guide to Setup - Login

A clear, step-by-step presentation-style guide to install Trezor Bridge, connect your Trezor hardware wallet, and log into your accounts securely.

Overview

This guide walks through installing Trezor Bridge — the local software that securely communicates between your Trezor hardware wallet and web-based wallets or apps. You’ll learn how to download, install, connect your device, perform the initial login and handle common issues. Follow each step carefully to keep your recovery seed and funds safe.

Prerequisites

System and hardware

A Trezor hardware wallet (Model One or Model T).
A computer running a modern operating system (Windows, macOS, Linux).
A supported web browser (Chrome, Firefox, Edge — latest versions recommended).
A USB cable to connect your Trezor to your computer.

Security checklist

Only download Trezor Bridge from the official Trezor website or verified sources.
Never share your 12/24-word recovery seed with anyone or enter it on a computer or website.
Keep your firmware up to date using official Trezor instructions.

Download & Install Trezor Bridge

Step-by-step

Open your web browser and navigate to the official Trezor website (search result may be spoofed — verify the domain carefully).
Find the Downloads section and choose Trezor Bridge for your operating system.
Download the installer file to your computer.
Run the installer: on Windows, double-click the .exe; on macOS, open the .dmg and drag to Applications; on Linux follow the distribution-specific instructions.
Complete the installation and allow any system permissions requested by the installer for USB access.

If your browser asks for permission to detect the device or install a helper, allow it only if you're certain the source is official. After installation, Trezor Bridge runs as a small background service that enables secure communication.

Connect Your Trezor Device

Physical connection

Connect your Trezor device using the supplied USB cable. The device should power on and show the welcome screen. If it does not, try another USB port or a different cable.

Authorize device

Open a supported web wallet (for example, Trezor Suite or a compatible browser extension). The web interface will prompt to connect — accept and confirm the pairing on the Trezor device itself by pressing the physical buttons when asked.

Login Steps

Initial login (first time)

Open Trezor Suite or the web wallet you plan to use.
Choose Connect Trezor and follow the on-screen prompts. The browser will communicate with Trezor Bridge to detect your device.
Confirm the connection on your Trezor device by pressing the buttons when the UI shows the expected words or symbols.
If the device is new, you will be guided to initialize it: set a PIN, write down the recovery seed (offline, on paper), and confirm seed words when required.

Subsequent logins

Plug in your Trezor, open the wallet interface, and choose your account.
Enter your PIN directly on the Trezor if required. The PIN is entered using the device’s screen; the computer shows a randomized number grid to prevent keyloggers from guessing your PIN.
Approve any transaction or login request on the device. Always verify the address and amount shown on the Trezor display before approving.

Troubleshooting

Bridge not detected

Restart your browser and computer.
Ensure Trezor Bridge service is running (on Windows check Services, on macOS check Activity Monitor).
Reinstall Trezor Bridge and grant required permissions.

Device not powering

Try a different USB cable and port.
Use a direct USB port on the computer (avoid hubs if possible).

Browser block or warning

Allow the browser to access the USB device only when you are sure it's Trezor. If you see certificate warnings, stop and verify the site URL.

Security Tips

Never enter your recovery seed into a computer or take a photo of it. Store the seed offline in a secure place.
Keep device firmware current using official instructions.
Verify every transaction and login on the device’s screen — not on the computer.
Use a strong PIN and consider passphrase protection if you need extra segregation of accounts (understand the risks before enabling).

FAQ

Is Trezor Bridge mandatory?

Yes, Trezor Bridge is the officially supported local bridge software that allows browser-based wallets to talk to Trezor hardware. Without it, many web-based interactions won’t detect the device.

Can I use Trezor with multiple browsers?

Yes — once Trezor Bridge is installed, most modern browsers will be able to use it. Make sure you grant USB access when prompted.

What if I forget my PIN?

If you forget your PIN and cannot unlock the device, you will need to do a factory reset and restore your wallet from the recovery seed. This is why storing the recovery seed securely is critical.

Conclusion

Installing and using Trezor Bridge is a straightforward process when you follow safe practices. Download only from official sources, protect your recovery seed, verify interactions on the device, and keep firmware and software updated. With those basics covered, your Trezor remains one of the most secure ways to manage private keys for cryptocurrency.
