Our very own f0dder made a nice little application that's good for storing private information.fSekrit
is the one. Just don't forget your password to unlock your passwords!
I also came upon a little program some time ago that will reveal a password underneath those asterisks. It was on one of those big lists of freeware, so I snagged it in case I ever needed it, but I've never had to use it yet. Although now that I think about it, I remember a time or two forgetting my FTP passwords and wishing I would have remembered to use it.
Anyway, it's a small little thing called Revelation which can be found at http://www.snadboy.com/
