Actually that's just giving someone your password, which is still one factor. Real two factor is like when you need your password plus a code from an app on your phone. I mean the whole point is having two different kinds of proof. If you just tell both things to the same person, it doesn't really add any security. Maybe it's just me but that kinda misses the point of having it in the first place.
Ever notice how people do the right thing but in the wrong way? Like @alice_craig said, sharing both parts misses the whole point. It's like buying a fancy lock but leaving the key right under the mat.
