Those running the third beta of iOS 6 noticed that Apple will make it easier to update applications and install free ones by removing an extra step necessary in the current iteration of the platform. Passwords will no longer be required for installation of free applications.
The user will also no longer be required to enter their iTunes password when updating an application already installed, regardless if it is free or purchased/commercial. Currently the system is asking you for authentication but in iOS 6, whenever tapping a free product in the AppStore in order to install it, the button will change to “install app” as pictured above. One other improvement is addressing an annoyance: when installing an app, the system will no longer revert you back to the home screen; instead, installation will be made in the background and you will not leave the AppStore.
The policy for commercial/paid applications remains the same: you will still need to enter your password and authenticate though the system will only ask you once every 15 minutes, as it currently does.
