How can i change email address for security questions and password resets

I've noticed that my password reset requests are going to an old email acount. In fact, i am not sure where they are going.

the real issue is that i don't see a way to change it when i am logged in (it took me many tries to actually log back in) to my apple id account.

I've changed alternate email accounts, but again i don't see a way to change my destination email account for security section of the account.

Also i would rather reset these via text (ATT has this option for my cell phone account reset and i love it). I don't see an option like that from Apple at all.

Any suggestions and help will be much appreciated. Don't want to struggle with password resets every time i need to get in.
