its been like that ever since psn came back up. if you want to get your password rest then you will have to contact sony in your country by email or phone support, they will ask security questions such as Dob username email address used to create the account and possable they will ask what was the 1st purchace on your psn account, they will then send a password reset email to your registered email address.
but you have to be quick as it only lasts 4 hours, so if you are not at home when the email arived you will have to contact them again. which is kinda dumb as they should make the link last longer.
hope that helps
