What is Trezor® Bridge?

Trezor Bridge is a dedicated communication tool that enables secure interaction between your Trezor® hardware wallet and web browsers. This background application facilitates the connection between your device and web-based interfaces like Trezor Suite without compromising security.

Unlike browser extensions that might have security vulnerabilities, Trezor Bridge operates as a standalone local application that creates a secure communication channel. It translates web-based requests into a format that your Trezor® device can understand, ensuring that your private keys never leave your hardware wallet during the Trezor Bridge login process.
