Microsoft announced on Thursday the general availability of multi-factor authentication for Windows Azure to add an extra security layer for users.
In a blog post, Microsoft said users may authenticate via an application on their mobile device, automated voice call, or text message with a passcode, all options that it said meet user demand for a simple sign-in experience.
Windows Azure Multi-Factor Authentication can be configured for various applications, including on-premises VPN, and can be run on existing on-premise hardware or in a Windows Azure Virtual Machine. Cloud applications like Office 365 and Dynamics CRM can also benefit from the added security layer, while MFA can also be added to custom applications using Microsoft’s SDK.
Office 365 is one of the most widely used email and collaboration platforms, according to a report on Thursday, and offers two-factor authentication as an optional feature with Office 365 dedicated plans.
Windows Azure multi-factor authentication will be available at two pricing options: $2 per user per month or $2 for 10 authentications.
AWS already offers MFA to offer users control over account settings, while Gmail has offered MFA since 2011 to provide extra email security to its users.
