There are even more improvements in OS X Mavericks, and the first of them is iCloud Keychain.
Craig Ferenghi says the new iCloud Keychain will keep track of website logins, credit card numbers, and Wi-Fi passwords, synced across iCloud to all your devices.
iCloud Keychain can also generate unique passwords for you, then automatically store them. And since this is all database stuff, it implies iCloud can now handle Core Data… a big failing in iCloud beforehand.
It’s all encrypted, too. Of course, with data vulnerabilities at an all-time high, whether you want to use iCloud Keychain might depend on how paranoid you were.
