iCloud Keychain is Apple's attempt to make a basic level of password management available to the mainstream. With it, your account names, passwords, and credit cards numbers can be stored in iCloud, and synced across all iOS 7 and OS X Mavericks devices that are logged in under the same Apple ID. In conjunction with Safari, it can also generate new, unique passwords, and autofill them when and as needed. All with 256-bit AES encryption. So, Apple has made it easier than ever to manage your passwords, but not necessarily simpler. There's still a lot to understand, and that's where iMore comes in. Here's how it all works!
