I am Vinod. I will try my best to help you resolve this issue.
Since you forgot the password for itunes, we can reset it by going to https://iforgot.apple.com/cgi-bin/WebObjects/DSiForgot.woa/wa
want tokeep same password as other members of family who dont live at home use this account to buy on itunes
Do anyone in your family know the password?
they only had access through my account as i wanted to restrict their buying on itunes
Unfortunately, we are not affiliated to itunes. If you want to know what is your current password, contacting itunes through email (by going to www.apple.com/support/itunes) may help you. I am not sure whether they keep information on your current password. If they don't, then you will have to reset the password and update that to everyone in the family.
