Thanks to a recent newsletter editorial from SQLServerCentral, I ran into Password Safe, which is a small program that allows you to protect all your passwords for web sites and online accounts, keeping them handy and safe at the same time. There's no install, just a small executable to run, and it will even enter your username/password combination to complete your login for you!
I've looked at other electronic 'wallets' in the past, but this one is the best I've seen to date...simple, direct, FREE!, and good at what it does. Being ignorant of the apparent power of the Blowfish algorithm, I'm still a little nervous to put 'all my eggs in one basket', but it sure is convenient.
