Under Mac OS 9, I used a program called VSE My Privacy to store my usernames and passwords for various types of online accounts, as well as credit card, bank account, insurance, and all kinds of other information. I liked it very much because it was a very easy to use program, very customizable, and secure because it used the blowfish algorithm to encrypt the stored data. I have searched for an equivalent OS X program to take its place, but have been unsatisfied with what I have found.
Then it occurred to me that I could use a much simpler method to store my information. I created a small encrypted disk image with Disk Copy, named it "Password List" and created category folders on the image. Within each category, I created a folder for the particular online service or account I wanted to store information about. Within each account folder, I dropped a link from Omniweb that points to the log-in page for that account, and text clippings of my username and password.
Now instead of having to use Classic to run VSE My Privacy, I can just mount the encrypted disk image and browse through it in panes mode to find the information. I just double-click the link to go to the web page, and drop the username and password clippings on the entry fields, and I'm good to go!
To store new passwords when I sign up for an online service, I just create another folder, and drop in the link to the login page and clippings of the username and password. This is also much easier now that we have spring loaded folders back!
