Report on users MFA status in Office 365 using PowerShell

During a recent audit we wanted to confirm what users had MFA enabled in Office 365. We use conditional access policy to enforce MFA.

We wanted to check each users to see if they had setup MFA and had a method configured. We also wanted to get information on licensing status and assigned licenses.

The only pre-req for using the script is that the MSOnline Powershell module is installed.

To install the MSOline module open and admin PowerShell windows and run

Install-Module -Name MSOnline

To confirm the module is installed run the below command.

Get-Module -ListAvailable MSOnline

First we need to connect to MS Online to do this run

Connect-MsolService 

Once connected to check the MFA status I will be using the StrongAuthenticationMethods properties as if MFA is configured for the user there will be a default method set.

For users that haven’t configured MFA no StrongAuthenticationMethods is set.

Below are the 4 methods available for MFA.

OneWaySMS
TwoWayVoiceMobile
PhoneAppOTP
PhoneAppNotification

In the script I only want to return the default method.

There is only one mandatory parameter for the export path where the report will be exported to.

The below is an example of how to run the report.

.\Office365_MFA_Report.ps1 -ExportPath C:\temp

Below is what the output will look like.

The full script can be downloaded from the below link.
