I think all common smuggler's abilities should be cover free.
Half of smugglers (who went to Scoundrel AC) do not use cover. And as result - some useful skills became absolutely useless.
While I am not 100% agree with you, but this security feature require a lot of work. I have mobile app on my phone to generate key. And I have physical device (came with my CE). Why cant I register both methods to get key?
