Core safety tips
For the safety of your assets, please remember the following principles:
Mnemonic phrase is the only way to recover assets: Never take pictures or screenshots of your mnemonic phrases, or save them to your phone, computer, or any cloud network. Be sure to keep the physical card in a safe place.
Beware of preset traps: If the device you received came with a preset PIN or a mnemonic card with words already written on it, Never use.
Keep your PIN safe: If you enter an incorrect PIN code 10 times in a row, the device will trigger the security protection mechanism and automatically reset the hardware wallet, erasing all data.
Advanced usage tips: This tutorial is designed to help you complete basic initialization. You can still follow up as needed at any time. Explore and manually activate advanced features like AirGap mode or UKey Seed Ti titanium plate backup.
