When you update your apps from the Updates tab in the App Store app, it doesn't prompt you for a password. If you try to update an app from any other section of the App Store app, it will ask you for a password.
Not having to enter your password to update or to download free apps was a rumored feature in iOS 6. I could have sworn it was officially advertised or at least confirmed by Apple itself, but I must be mistaken. Anyway, it wouldn't matter if someone could download free apps onto your stolen phone.
Why you want disable ? That's protect your pocket 😀
If you unlucky , get stolen or something , they purchase the app for $999 ( have some app on AppStore ) and what will happen to you ??
