Apple’s CEO Tim Cook said the company plans to extend its two-factor authentication system to logins to the iCloud service from mobile devices. The change will come when iOS 8.0 comes out later this month. Apple has had 2FA available for iTunes and Apple ID accounts since March 2013, but it is not enabled by default and it doesn t apply to iCloud logins at this point. The company has not widely publicized the availability of the 2FA option, something that security experts have criticized the company for.
