iCloud Keychain Removed in iOS 7 GM
Apple appears to have removed iCloud Keychain support from the iOS 7 Golden Master (GM), which was seeded to developers yesterday. While iCloud preferences previously listed iCloud Keychain, the option has now been removed, suggesting that the initial public release of iOS 7 will not include the function.
iCloud Keychain is also newly tagged as "Coming soon" on Apple's iOS 7 feature page and while it is unclear why it has been removed from the GM, it is likely that Apple has chosen to provide the feature alongside OS X Mavericks, which is slated to be released later this year.
First introduced at WWDC, iCloud Keychain is Apple’s new cross-device password manager, designed to share and store passwords across all of Apple’s products running iOS 7 and OS X Mavericks. In addition to passwords, iCloud Keychain also stores website logins, credit card information, and Wi-Fi networks.
