With the release of iOS 6 beta 1, we learned that Apple was making it a little easier to downloaded updates to your already-existing apps by ditching the Apple account password prompt. Now, it looks like Apple's going to get rid of the password requirement in even more scenarios.
Cult of Mac spotted that in iOS 6 Beta 3, you are no longer prompted to enter your Apple password when "purchasing" a free app. So the only time you'll ever have to key in your password is when you're actually buying a paid app.
This small change is definitely not one of the most earth-shattering tweaks to iOS that will come with iOS 6, but I'll be damned if we shouldn't rejoice in the elimination of something that's annoyed me for years.
Of course, one could make the argument that this will make it more likely that a person will download an app they really didn't want to - or a child could download an app that's not-safe-for-children without the parents' knowledge. But hey, it's only the free apps that no longer require a password - you can always just delete them. This is one little update that I'm sure most iOS users can get behind.
