iCloud Keychain works has frustrating limitations
I’ve long been a fan of 1Password, but have often said that it’s functionality is important enough to be built into the OS as an expansion of the Keychain that’s been part of OS X since, well, forever. iCloud Keychain finally makes a move towards that and I’ve been using it on Mavericks and iOS 7. But it still doesn’t replace 1Password for me. Instead, 1Password has become the master place where I access and manage my information while letting iCloud Keychain enable that information to be used across my devices.
This is pretty much how I feel as well and how I use 1Password with iCloud Keychain. 1Password has a lot more functionality (that I use) than iCloud Keychain, but iCloud Keychain is integrated with Mac OS and iOS, which makes for a better experience for web site logins.
