CONNECT
Plug in your device
Connect your Trezor to your trusted computer or phone using a compatible cable. Follow any instructions displayed on the device. If a prompt asks you to visit a web address, independently verify it before continuing. A new device may need its firmware installed; this is a normal part of setup when performed through official Trezor software.
Keep the device connected while an update completes. Do not disconnect it during installation, and do not follow instructions from pop-ups or unsolicited messages. If your screen shows a warning you do not understand, stop and consult official support rather than guessing.
