If you’re like me, you’ve got about a zillion passwords to keep track of. Password Safe is a decent free password manager. Basically, its specialized database for keeping track of your password info in a secure manner (they are stored encrypted) I’ve been using it myself for a couple of years now, but didn’t realize how much better the latest version is (stuff like groups for organization, auto lock program after X minutes). Definitely worth a look.
As a bonus, it even intelligently imports data from previous versions of the program (and it keeps a backup of the original data, sweet!)
