By now you've probably heard about CelebGate — the nude photo hack that has Apple users worried about the security of their online data.
The hackers gained access to celebrity photos via iCloud, Apple's online storage service.
Apple CEO Tim Cook announced that there would be iCloud security updates. Those updates will alert users when someone tries to access your iTunes or iCloud accounts from a new device. Users will also be alerted when anyone tries to change the password on their account.
That notification system — often called two-step or two-factor authentication — only works for iTunes right now. It will work for iCloud when iOS 8, the new operating system for iPhones and iPads, rolls out this fall. Still, it's something you should set up now.
