In iOS 5 and earlier versions of iOS, from the App Store before downloading free apps or updating the apps which users had already installed on their iDevice, every time they had to give their Apple ID Password. To some users it seemed unnecessary and annoying to enter password while downloading free apps. The good news is that unnecessary and annoying dialogue is no more. In the iOS 6, users won’t have to give their Apple ID Password to download free apps or update apps.
In iOS 5, users must enter their password whenever they wish to download any paid or free app. Even at the time of downloading an update of a particular app, they are bound to enter password. But in iOS 6, users don’t need to enter password. Earlier we reported that Apple users don’t need password in iOS 6 for software updates and downloads of previous purchases. iOS 6 Beta 1 debuted in early June. After its release users no longer needed to enter their iTunes password when downloading updates or previous purchases from the App Store.
After the release of iOS 6 Beta 3, Cult of Mac discovered that iOS 6 Beta 3 users like iOS 6 Beta 1 users don’t have to provide Apple ID Password as well while downloading free apps or updating apps. Upon pressing the ‘Free’ button on the App Store, the button changes to “Install App” and another press begins the install process. Besides, to make the purchasing process quicker and easier, the App Store no longer returns users to the home screen when an app is purchased. Instead, it downloads in the background, making the purchase of multiple apps much easier.
Though pressing some buttons/keys while downloading/updating apps doesn’t take too much time, but still some users become happy as they got rid of from doing this boring work.
