iCloud is a cloud service provided by Apple. A basic iCloud account is free and provides a connection to calendars, contacts, and other services that integrate with your Mac. Because iCloud has services that integrate with the Mac, it’s more than a traditional cloud solution, though. An iCloud account has options that include tracking the physical location of your Apple devices and potentially escrowing keys used for decrypting hard drives and remotely controlling computers. Because the iCloud account provides access to your computer, securing the account and the connection between the computer and the account is of paramount importance. This security starts with the Apple ID and extends to the settings used when setting up iCloud-based services on your Mac.
