Apple began rolling out its two-step verification system for your Apple ID last year, adding an extra layer of protection for users. Now it is making the security feature available in more countries — including Canada, France, Germany, Japan, Italy, and Spain.
The concept of the two-step verification system, for those unfamiliar with it, is to make you enter a code (sent to a single trusted device) each time you make changes to your account, or make a new iTunes or App Store purchase using a new device.
