forgot pass for kdewallet

it just kept bugging me to use it. so i used it once and forget the pass. how can i delete this bothersome software? i know what is in it but the program stops me from logging in even though the name and pass are correct!

open kwalletmanager and delete the wallet.

thx. i will find out if it works the next time i use that site. in about two months. i booted into windows to do the business. many thanks.
