I try a good bit of software - and in doing so waste a good bit of time. One Password, though, has become my most reliable repository of critical information. "Yes" I can say to my wife and children - "I do know your Social Security number" / "Our Frequent Flyer numbers on the airline we only flew once 3 years ago" / "the password to your Lego account that was on a post-it note until you decided you were too coll for Legos." It's not so much utility as it is the gateway to small moments of morale superiority for the ones you love.
