Over the last few months we’ve been sharing more insight into what’s in it for the enterprise when it comes to using Windows Azure.  Today we’re announcing a new service code named Active Authentication, which will allow enterprises to secure employee, partner, and customer access to cloud applications with multi-factor authentication. 

Starting today, companies can enable multi-factor authentication for Windows Azure Active Directory identities to help secure access to Office 365, Windows Azure, Windows Intune, Dynamics CRM Online and many other apps that are integrated with Windows Azure AD.  Developers can also use the Active Authentication SDK to build multi-factor authentication into their custom applications and directories.
