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.
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.
While Mavericks will not be available until later in the fall, iOS 7 will be released to the public on September 18, ahead of the release of both the iPhone 5s and the iPhone 5c.
