Trezor Bridge is an essential component for Trezor hardware wallets, serving as the secure communication link between your Trezor device and your computer. Unlike simple USB connections, Trezor Bridge ensures that your Trezor wallet can safely interact with the Trezor Suite software or compatible web applications while maintaining the highest level of security. This guide explains what Trezor Bridge is, why it is important, how to install it, and best practices for maintaining a secure connection.
