You have to manually enter your Apple ID password to turn on Touch ID for the App Store the first time. Thereafter all that is needed is the Touch ID. However, you will have to enter your six digit ID any time you restart your iOS device to reactivate Touch ID. You may have to re-enter everything after an iOS upDATE or upGRADE as well.
