Pass words.

I have a problem with passwords. These words I pass around to save on my computer to log in to certain sites. I know they are important to protect me from Internet harm, but I have so many I cannot keep track of them. I try to save them with my Internet saving password type tools, but every now and then I have to change them and they save my old password not the new one and I usually forget the new one. Then I try to retrieve these passwords and they ask me secret questions which I forgot the answer to. Do you have any solutions to this password delimna?
