If you're using a Trezor hardware wallet — whether it's Trezor Model One, Model T, or the Trezor Safe series — you may need Trezor Bridge® to enable communication between your browser and device. Trezor Bridge acts as a secure connector, allowing your wallet to interact with Trezor Suite and web interfaces without exposing your private keys or seed phrase.
This guide explains what Trezor Bridge is, why you may need it, how to install it safely, how it works behind the scenes, and troubleshooting steps if your device isn't detected. By the end, you'll be fully confident using Trezor Bridge to manage your crypto safely.

If switching fully to the Trezor Suite desktop app, you can remove Bridge:
Removing Bridge doesn't delete keys — they remain on the Trezor hardware wallet.
