Evil mastermind PhD Evil, is trying to destroy the north pole. In order to foil his plan you need to log on to his computer. Alas you don't know the password, thankfully PhD Evil thinks he is too clever. So he left a puzzle to solve his password.
My password is 2
It is ten too.
My password is seven letters long
four letters is also not wrong
It is fair to say that it is none
but that could be off by one
If you think my password is a single hole,
I will blow up the north Pole!
Your partner says, I don't really care the north pole is fake. But you persevere for Santa's sake.
What is the password?
