I wouldn't do that if I were you, if he catches you and you were in the wrong it would cause a big problem in the relationship.

But if you really want too, then there is no need, just check his texts/facebook when he is asleep or something

Pretty sure she would've done that ages ago.
But she hasn't which leads to his phone being locked with PIN Code/ Password or Finger print scan.
