DirectAccess 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).
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.
You can download a fully-functional trial version of PointSharp ID here (registration required). The PointSharp ID and DirectAccess integration guide with detailed step-by-step instructions for configuring DirectAccess and PointSharp ID can be downloaded here. Consulting services are also available to assist with integrating PointSharp ID with DirectAccess, VPN, Exchange, Skype for Business, Remote Desktop Services, or any other solution that requires strong user authentication. More information about consulting services can be found here.

Implementing DirectAccess with Windows Server 2016
Posted by Richard M. Hicks on March 27, 2017
I’m pleased to announce that I will be delivering a community theater session at this year’s Microsoft ignite conference in Atlanta, GA. The session, THR2136 in the session catalog, is scheduled for Thursday, September 29 at 12:40PM. This is a level 200 talk where I’ll be providing a high-level overview of all remote access technologies in Windows Server 2016, including DirectAccess, client-based VPN, and Web Application Proxy (WAP). I’ll be focusing on what’s new in each of these technologies and demonstrating how each solution applies in different use cases.
In addition to the session, I’ll be spending time with the folks from PointSharp and Pluralsight in their respective booths too, answering questions and providing demonstrations. I hope to have copies of my new DirectAccess book to sign as well. Be sure to follow me on Twitter for up-do-date details. Hope to see you at the conference!

Integrating multifactor authentication is essential for providing the highest level of security and assurance for DirectAccess clients. Smart cards work well for this, but they impose a heavy burden in terms of expense and administrative overhead. A more effective alternative is to use a One-Time Password (OTP) solution such as PointSharp ID.
To learn more about the PointSharp ID OTP solution and how it integrates with DirectAccess, join me for a live webinar on Tuesday, July 27, 2106 at 10:00AM PDT where I’ll discuss the following topics.
- What DirectAccess security risks can be mitigated with OTP?
- What are the supporting infrastructure requirements for OTP authentication?
- How to integrate the PointSharp IP solution with DirectAccess
