This short presentation explains what Trezor Bridge is, why it matters, how it works, and practical tips to keep your hardware wallet connection secure.
Trezor Bridge is a small application that runs on your computer and provides a secure communication channel between the Trezor hardware wallet and web interfaces such as Trezor Suite or compatible web wallets. It replaces direct USB browser access with an intermediary service, improving compatibility and security.
When installed, Bridge opens a local endpoint (only accessible from your machine) and translates browser requests into the protocol the Trezor device understands. The wallet UI communicates with Bridge via secure, local messages; Bridge relays commands to the Trezor device and returns signed responses.
Bridge does not hold or transmit private keys. All critical operations remain on the hardware device. Bridge only forwards commands, and user confirmation on the device is required for sensitive actions such as signing transactions or exporting public keys.
Always download Bridge from the official source to avoid tampered installers. Keep Bridge up to date to receive security fixes and maintain compatibility with the latest browsers and OS updates.
If the device is not detected: check USB cables/ports, restart Bridge, allow permissions if prompted, or reinstall Bridge. If browser warnings appear, ensure Bridge is running and the browser is allowed to reach the local Bridge endpoint.
For advanced threat models — for example, a compromised host system — Bridge alone cannot protect you. In such cases, use an isolated, trusted machine for signing, or air-gapped workflows where the host has no network connection.
Trezor Bridge provides a secure, local, and user-friendly way to connect your hardware wallet to web interfaces while keeping private keys safe on the device. Use official downloads, keep software updated, and follow device and software hygiene to minimize risks.
