[Several people have asked me about this, so I've created this short explanation...]
Saving Passwords in Internet Explorer 6
This is what you need to do to get Internet Explorer 6 to start remembering passwords for you:
First, go to Tools --> Internet Options in the pull-down menus.
Then, go to the Content tab.
Click on the AutoComplete button toward the bottom...
...and in that form, turn ON the User names and passwords on forms option (and the Prompt me to save passwords on forms option below it.)
The next time you log into your favorite website IE will ask you if you want it to remember that username and password.
Choose Yes, and the next time you go to the login page, just click in the Username spot. Your username will appear in a little dropdown menu there, and you can choose it from the list.
Once you do,your password will be automatically filled in below.
Click the Log in button, and you're in! :-)
