Following a seemingly endless series of hacks that have afflicted cloud service providers like Evernote and Dropbox, Apple has just introduce two-step verification for your Apple ID, which makes you enter a code (sent to a single trusted device) every time you make changes to your account or make a new iTunes or App Store purchase from a new device.
The idea here is to make it harder for hackers who have stolen your Apple ID login details to actually do anything with that information without access to a specific device (like, say, your iPhone). To make any big changes on your Apple ID, you’ll need both the hardware and the login details.
To sign up for two-step verification, go to Apple’s Apple ID subssite, login with your Apple ID and then select “Password & Security” in the sidebar to get started.
Sadly, two-step authentication apparently only works right now in the U.S., UK, Australia, Ireland and New Zealand. English speaking countries. Expect to see a more international rollout of this feature soon.
