There have been hints for the past week-plus -- courtesy of Liveside.net -- that Microsoft was poised to roll out two-factor authentication for its Microsoft Accounts. On April 17, Microsoft did just that.
The company is calling this security process "two-step verification." Microsoft is making available two-step verification across all products and services accessible via a Microsoft Account. This includes Windows, Windows Phone, Xbox, Outlook.com, SkyDrive, Office, and more. The rollout will be happening over the "next couple of days," according to the company.
(Microsoft Account is the new name for Microsoft's Live IDs.)
