DirectAccess and Azure Multifactor Authentication

Introduction

DirectAccess and Azure Multifactor AuthenticationDirectAccess can be configured to enforce strong user authentication using smart cards or one-time passwords (OTP). This provides the highest level of assurance for remote users connecting to the internal network via DirectAccess. OTP solutions are commonly used because they require less administration and are more cost effective than typical smart card implementations. Most OTP solutions will integrate with DirectAccess as long as they support Remote Access Dial-In User Service (RADIUS).

DirectAccess and Azure Multifactor Authentication

Azure Authentication-as-a-Service

Azure Multifactor Authentication (MFA) is a popular OTP provider used to enable strong user authentication for a variety of platforms, including web sites and client-based VPN. Unfortunately, it doesn’t work with DirectAccess. This is because Azure MFA uses a challenge/response method for which DirectAccess does not support. To use OTP with DirectAccess, the user must be able to enter their PIN and OTP immediately when prompted. There is no provision to begin the authentication process and wait for a response from the OTP provider.

PointSharp ID Multifactor Authentication

An excellent alternative to Azure MFA is PointSharp ID. PointSharp is a powerful OTP platform that integrates easily with DirectAccess. It is also very flexible, allowing for more complex authentication schemes for those workloads that support it, such as Exchange and Skype for Business.
