Let's Learn Azure Multi-Factor Authentication today!!!

Multi-factor Authentication is critical in today's world. Many Organizations already adopted this model from a long time and today's blog post is written to provide you with some essential resources with a Quick demo to experience the benefits of Azure MFA.



What is Azure Multi-Factor Authentication?

Multi-factor authentication (MFA) is a method of authentication that requires the use of more than one verification method and adds a critical second layer of security to user sign-ins and transactions. It works by requiring any two or more of the following verification methods:
  • Something you know (typically a password)
  • Something you have (a trusted device that is not easily duplicated, like a phone)
  • Something you are (biometrics)                              



Multi-factor authentication is a method of verifying who you are that requires the use of more than just a username and password. It provides a second layer of security to user sign-ins and transactions.
Azure Multi-Factor Authentication helps safeguard access to data and applications while meeting user demand for a simple sign-in process. It delivers strong authentication via a range of easy verification options—phone call, text message, or mobile app notification or verification code and 3rd party OATH tokens.

How it works ?

Be sure to read to know the Pricing 

Most important part to review to adopt the best one for your needs

Choose the multi-factor security solution for you

On premises or cloud


These are the basics to begin your learning.

Microsoft has provided great documentation articles as one of the essential resources when you begin your learning with Azure MFA.

For Office 365 below is the essential one


Currently we have about 40 documentation available on the Azure MFA topic and you can access them below


Some vital articles to read for a successful MFA deployment
  • Directory integration between Azure MFA Server and Active Directory
  • Getting started with Azure Multi-Factor Authentication and Active Directory Federation Services
  • Getting started with the Azure Multi-Factor Authentication Server
  • Securing cloud resources with Azure Multi-Factor Authentication and AD FS
  • Secure cloud and on-premises resources using Azure Multi-Factor Authentication Server with AD FS 2.0
  • Secure cloud and on-premises resources using Azure Multi-Factor Authentication Server with Windows Server 2012 R2 AD FS
  • Azure Multi-Factor Authentication FAQ

Update:

Review the new Security Best practices article for Azure MFA



More Organizations already use ADFS to secure their environment and now with MFA it adds more one more layer of strong authentication to provide a highly secure access to end users without compromising the Organization's Information Security.

Once you are done with the documentations, you can view some demos with deep dive discussion from Microsoft Virtual Academy course intended on this topic




Its now time for a Quick demo walk-through with my own experience.

I have setup MFA in the cloud and chose Azure Multi-factor authentication for my Office 365 users.

*You can Setup MFA from Office 365 Portal for free and additionally you don't need create a Authentication provider as shown below, I am planning to use some advanced features so, explicitly selected Azure MFA in Cloud for demo.

Also Azure MFA comes as a part of your Azure AD premium and EMS.

Here is the Azure portal view showing my Multi-Factor Authentication Provider


I have selected a test account and configured the Authentication contact info with my Mobile number



Already my test account is enforced for MFA and below is the snapshot




If I navigate to the Service Settings, I have options to configure App passwords, Skip multi-factor authentication for federated users in the intranet and also Suspend MFA for remembered devices.




Since I have already configured the Azure Multi-Factor Authentication as Authentication provider, I can take advantages of the advanced features.

I can Navigate to the MFA portal by accessing the Go to the Portal Hyperlink

  

For Instance I am showing an example of Usage Reports, I can generate the report for a set of time frame for analysis.
  


More options are available and the above one is an example.

Lets get in to the end user experience, My user is trying to access his Office 365 Webmail and below is the experience he gets before successfully authenticates to his inbox.




If you take a look at the steps Pic 4 Indicates the user is authenticating for the call he received and after successful authentication he will be accessing his inbox, which is shown in Pic 9.

voluntarily failed the authentication to show you the another method, using Text message with the Verification code.

In Pic 5 the authentication is failed and user is provided with alternative options in Pic 6 I am selecting the Text Me option and successfully receiving the code in the next pics and finally accessing my Inbox.

This is a pretty regular experience and with Azure MFA we can do more, hope this one is quite good with a quick demo.

Update:

Review the below excellent office blog post showcasing end user experience with MFA

Sign in to Office 365 with a second verification method

Up Next, We have the Office 2013 device apps now support multi-factor authentication through the use of the Active Directory Authenticaton Library (ADAL). Currently this is in preview and you can test this by enabling Modern authentication for your tenant.

You can refer the Plan for multi-factor authentication for Office 365 Deployments guide for more details on the topic.

Update:

Modern Authentication reaches GA

Updated Office 365 modern authentication public preview

Before I conclude, I want to share you with one more great TechNet blog post, I came across recently that is pretty new and shows us how to use MFA Support for Windows Azure Active Directory PowerShell Module.


Hope this write-up is quite useful for readers to know Azure MFA a bit better with the curation of various resources under a single window with bits of my own experience and learning.

Update:

Microsoft AD team is publishing Azure AD Mailbag series with rich set of information on Azure AD. We also have the MFA Q & A available as a part of the series.

I recently came across this excellent walk through from one of the MFA Q & A series, that makes you understand the logic flow of AD FS and MFA Server as it works with Azure AD.




Access here: Azure AD Mailbag: MFA Q&A, Round 3!
