I am new with the LastPass autenticator. Does 2 left mean 2 left today (then tomorrow it starts over at some other number?) or "2 left" period. And if only 2 left period, then does this mean it will no longer work unless i pay? and what do they mean by "switches". I tried to get in Yahoo mail on my PC and in order to do so I must authenticate with lastpass on my phone. so what exactly am i switching?
and what is an active device type?
