I use a number of passwords, but have difficulty remembering them, particularly when returning to a little-used password protected website.
To help me out I use Roboform. It stores usernames and passwords iand any other personal stuff in an encrypted file. After you've been to a page or site once and filled in the details manually it will remember the details for that page/site and offer to fill it in for you on subsequent visits.
You can protect this activity and all the encrypted data and edit functions with a master password. Roboform will then only fill in the blanks on a page or allow you to view/edit current data if you provide the master password, so if someone knocks off your lapptop or gets into your PC they can't maliciously use the automation the program offers or the info it contains.
Works with IE, Slimbrowser, Firefox, Netscape and maybe some others. Not Opera, unfortunately. See
Roboform
5 stars, IMO.
