Perhaps when you put your finger on the home button it would read your fingerprint and authenticate you like that and the user wouldn't have to enter their password into a box that might steal it.. I can spend thousands using just my fingerprint, but authorising my Apple ID so I can buy a 99p app or login into iMessage requires my Apple ID password...
