Passwords are a necessary evil. They slow us down and get in the way when we want to just “get some work done”. I can’t tell you how many times I have heard from a friend or client “can’t we just not use passwords?”, “why do we need them anyway?”. Why indeed. Passwords provide a method of identifying who you are. As an analogy, imagine that someone walks up to you and starts talking to you. They start off by saying “Hi, I am you friend Mary”. Now if you can see her face and you know her voice you know who Mary is and the rest of the conversation flows easily; you know what information you can and can’t share with Mary. Now pretend that you are blind and that everyone sounds the same. How would you know that was Mary you were talking to? Just from her telling you who it was, what is to stop anyone from just starting off the conversation the same way? You would have no way to confirm that you were talking to Mary.
