Second iOS 6 password removal -- first was upgrades and reinstalls
(Updated with conflicting accounts) Advancing the password-removal trend that started with beta 1 of iOS 6, the latest build no longer requires a password when downloading free apps. The first beta of iOS 6 allowed developers to re-download purchased applications and updates without entering the iOS App Store account information, making this change an extension to the password removal. Many of the items available on the App Store are free, and do not charge the user's account.
As it stands with all current versions of the iOS, any App Store or in-app purchase requires password entry. The App Store currently returns the user to the home page after selecting "install" following password entry. The beta 3 of iOS 6 downloads the application or update in the background, leaving the user on the App Store screen.
Brief testing by MacNN has proven that in-app content and apps with an associated cost still require a password entry in the new version of the beta, but only once per every 15 minutes. An Apple representative told MacNN that "features in iOS 6 are subject to change. We have no comment if the password requirements in the current beta will remain the same for the launch."

Update: Some accounts are inconsistent, even indicating that Apple is flipping back and forth between requiring a password. Apple may be testing systems behind the scenes.
