If you got "IKWID MODE" on top of your BC Vault display, do not panic :) You did hold the middle button on the device when you connected it to the USB port.

IKWID means "I Know What I am Doing" and is a special mode (we came up with that acronym after a long brainstorm of how to call it) used for reveal of private keys stored on the BC Vault. See this KB Article about it.
