I just checked and between my wife and myself, we have more than 311 ID/password combos. Many of these have been around for a long time and are no longer used, but they ARE all different. The trivial ones get simpler passwords than the ones associated with banking. We keep all of them in an industrial strength encrypted database called "mSecure". It has versions for our Apple Mac equipment and for iOS devices. That means we have them available whenever we need them. Soon, they'll support the iPhones' fingerprint sensing technology so we won't have to enter the long password to get in.

I don't know if there's support for other platforms, but I'm sure there are at least similar encrypted database programs on other devices.

Hopefully the NSA isn't snickering at my naiveté right now!
