Check your device
BEFORE YOU BEGINUnbox your Trezor and look it over. Your device should not arrive with a pre-written recovery phrase, PIN, or wallet already set up. If anything looks tampered with or unusual, do not use it; contact Trezor Support through trezor.io/support.
Only use the official cable or a reliable data cable. Avoid public computers and shared devices for setup. If your device came from somewhere other than an authorized source, take extra care to confirm its authenticity using Trezor’s official guidance.
