Xbox Live gets new authentication system

Microsoft has announced a change to security measures for its services, including Xbox Live.

Skype, Windows and Xbox Live users will have the chance to upgrade to a two-step system for tighter security.

A secondary email address or telephone number will then be used for back-up authentication.

"Microsoft has increasingly focused on delivering connected devices and services that are currently used by more than 700 million people around the world," read a Microsoft statement.

"A Microsoft account is the key that unlocks your experience across these products, from your Windows PC to your Windows Phone, from Xbox to Outlook.com, from SkyDrive and Skype to Office and much more."

Microsoft hopes one password system will be used across multiple devices in the future.
