Developers can also update their apps to use keychain, if the app is on a device that uses iOS 7.0.3 or later, or OS X Mavericks 10.9 and later.

What happens when I turn off iCloud Keychain on a device?

When you turn off iCloud Keychain for a device, you're asked to keep or delete the passwords and credit card information that you saved. If you choose to keep the information, it isn't deleted or updated when you make changes on other devices. If you don't choose to keep the information on at least one device, your Keychain data will be deleted from your device and the iCloud servers.
