Is it possible to reset iphone password?

So i found a good deal on craigslist but the guy said he forgot the password but i can go on itunes to change it, is that true?

You can't change it if you don't know it. Your only option Is to 'restore' the iPhone. Which resets it to its factory settings, as if you just bought it. So when you get it, restore it.

You sure he didn't steal it?
