Look, we all have to stay on top of this password thing by using ones that aren’t guessable and changing them from time to time to stay safe. That said, you don’t have to worry about most big-name websites, including Facebook and Google, giving anyone your password. Why? Because they don’t know it. Really. They can’t even give it to you when you forget it. That’s why you have to reset your password if you can't remember it.How this all works is so clever and simple, I think it’s ingenious.
