Use strong (long, random) passwords. Practice them.: "Many people have heard that passwords should never be written down, but that rule was for U.S. government employees who had to protect secret information from spies rummaging through their desks. You don't have to be concerned about that (I hope).

It is a huge security risk, with a high probability that somebody will exploit it, to use a weak password because you're afraid of writing it down and a weak password is the only kind you can memorize. "
