Manage Saved Ie Passwords
When you enter a user name and password, Internet Explorer may ask if 
you want it to remember the password. Click on Yes and it will 
automatically fill in the password next time you enter that user name. 
But if you check Don't offer to remember any more passwords, then 
whether you click on Yes or No, you won't be prompted again. To recover 
this feature, launch Internet Options from IE's Tools menu, select the 
Content tab, click on the AutoComplete button, and check Prompt me to 
save passwords.
To delete an individual saved password entry, go 
to the log-on box on a Web page and double-click. Your saved 
AutoComplete entries will drop down. Use the arrow keys to scroll to the
 one you want to delete, and press the Del key.
