MFA Introduction

Multi-factor authentication (MFA) in D365FO.

Dynamics 365 supports Multi-Factor Authentication (MFA) or Two-factor authentication (2FA) which is a form of multi-factor authentication. Multi-factor authentication is an increasingly common and more secure method of protecting access to sensitive information or services by requiring an additional method of verifying your identity. The additional verification method occurs through different mediums such a text message, email, phone call or smartphone application. At its core, multi-factor authentication is just the additional requirement for you, to verify you are who you say you are in addition to your username and password.

Multi-Factor Authentication in your daily life

Here is an example of MFA you might encounter every day. When I log into my bank’s website, I have to enter my username and password.  However, before I gain access to my information, I also have to provide a PIN number that the site sends to me via text message. If I enter the PIN in the allotted time, I have verified to the bank’s satisfaction I am who I say I am. If I don’t, I will not be allowed access to the online banking portal. It’s simply a more secure means of preventing access to sensitive pieces of data by the bad guys. We consistently read about username and passwords being hacked, however with MFA, this additional authentication requirement is less likely to be comprised at the same time. Your username and password might get comprised, but it’s less likely that in addition to those pieces of information being stolen that your cell phone would be taken as well hence potentially thwarting any attempt to access your online information (if you have MFA setup of course).

So, who uses multi-factor authentication?

A vast majority of online services offer MFA. Banks, Twitter, Facebook, Credit Card Companies, Google, Microsoft, these are all examples of companies that offer services that can use multi-factor authentication.  It requires a little effort to initially setup (trivial) and of course the requirement that you have access to the additional authentication method you selected once enabled (which can sometimes be a pain point). 

Enabling MFA in D365 - Admin Side Setup

Login to www.office.com à Click on Admin

Click on Users --> Active Users

 Click on User --> Click on Manage multi-factor authentication

Select Check box for selecting User --> Press Enable

Then Click on enable multi-factor auth

Getting started with multi-factor authentication for Dynamics 365.- User Side.

There are two Stages Authentications

1. Normal Password Authentication - First Stage Authentication

2. OTP or Call Verification Authentication - Second Stage Authentication

First Stage Authentication (Normal Authentication)

Enter User and Password as First stage authentication

Second Stage Authentication (OTP)

For Second Stage authentication, Click on next in below screen.

In Additional security verification window,

1.       Enter Mobile number for Microsoft contact you

2.       Select a Method of way Microsoft contact you either text message (sms) or call

3.       Click on next

1. Check the Mobile phone SMS
2. Enter the code
3. Click Verify

Click on Done to finish second stage authentication.

User will be successfully logged in to system after two-stage authentications. i.e. Muti-factor authentication

Next time when user sign into system using username and password, it will prompt below screen for second stage authentication and User phone will get a text message and type it in to validate account properly.

Note. To access system using MFA user must keep configured mobile phone for OTP verification.

Change phone number which is already given in Second StageAuthentication
