I need a card to open the door. I need a log-on name and a password to start my desktop computer and another to get into the system. I need to punch a bunch of buttons to retrieve my voice mail. All that in less than five minutes. All in the name of convenience.
Passwords are undeniably useful, even necessary.
Problem is, one ID isn't enough. Well, we don't actually need them. One of each would probably do. But the password police say that would be dangerous. So we're not only supposed to have different passwords and PINs for every personal account, we're also supposed to change them as often as we change our bedsheets.
