Apple on Monday appears to have rolled out a new implementation of its two-factor Apple ID authentication system with iCloud.com, requiring users who have the additional layer of security enabled to enter a special code before accessing the Web apps. With the new implementation, Apple is expanding its two-step authentication security feature beyond Apple ID management and iCloud-connected features to the iCloud.com Web app suite. Prior to the change, iCloud.com was accessible via a simple password. The feature was first spotted by reader Stephan. AppleInsider was able to confirm the new iCloud security feature is indeed Apple's normal two-factor authentication service, though it is unclear if the feature is in testing or nearing rollout. Certain Apple ID accounts we tested required the second verification, while though others did not.
