What is Trezor Bridge?

Purpose & function

Trezor Bridge is a small helper application that provides a secure communication channel between your Trezor hardware wallet and web-based wallet interfaces (for example, the Trezor web app). It replaces direct USB communications in a way that improves compatibility and security on modern operating systems.

Key points

Acts as a local server to handle encrypted messages.
Allows browsers to talk to Trezor devices without native USB support.

Why Trezor Bridge matters

Security & usability

Bridge minimizes attack surface by restricting access to local machine processes and making firmware-level operations explicit to the user. It also smooths the installation workflow so users can focus on securing their seed and device.

Advantages

Improved cross-browser compatibility.
Fewer manual drivers to install.

Installation — step by step

Windows / macOS / Linux

Download the official Bridge installer from the vendor, run the installer as administrator if required, then connect your Trezor. Always verify the download was obtained from the official domain and check checksums when available.

Checklist

Use official site only.
Close other wallet apps before installing.
Allow network exception for localhost if prompted.

Secure connection tips

Make your setup robust

Always confirm the device's on-screen prompts before approving transactions. Keep Bridge and device firmware up to date. Use strong OS credentials and avoid public or untrusted computers for signing transactions.

Pro tips

Enable automatic updates where safe.
Use a dedicated machine or VM for high-value operations.

Troubleshooting common issues

Connection fails or browser can't detect device

Restart Bridge, try a different USB cable, ensure the device is unlocked, and check browser permissions. If problems persist, consult official troubleshooting guides before attempting risky fixes or third-party drivers.

When to seek help

Persistent detection failures after reinstalling Bridge.
Device firmware prompts that you don't recognize.

Advanced & enterprise notes

Scaling and audits

For teams, adopt standard operating procedures for signing workflows: review transactions with multiple approvers, use watch-only accounts for monitoring, and schedule firmware audits. Avoid sharing seed phrases and use passphrase feature if applicable.

Best practices checklist

Your quick security audit

Download Bridge only from official sources.
Keep firmware & Bridge current.
Confirm on-device prompts for every action.
Store seed in a physical, fireproof place.
