Air Gap Mode

AirGap Mode refers to a security measure where your OneKey Pro is completely isolated from other devices and networks. This isolation prevents any potential remote attacks trying to access your digital assets, disabling Bluetooth, USB, and NFC transfer function.

To enable AirGap Mode on your OneKey Pro, follow these steps:

  1. Unlock your OneKey Pro device and navigate to the "Settings" menu.
  2. Select "Air Gap Mode" from the menu.
  3. Toggle on "Air Gap" to enable the Air Gap Mode.
  4. You'll be asked to confirm your action. Tap on "Enable" to activate the Air Gap Mode.

With the Air Gap Mode enabled, your OneKey Pro operates independently, ensuring that your digital assets are stored in the most secure environment.
