How to obtain list of users if SMS MFA is enabled using PowerShell

Hello @Christopher Rugama ,

Welcome to the MS Q&A forum.

I played with the script from this post and below is the updated version which returns data required by your ask.

 Function Get-PerUserMFAStatus {   
    [CmdletBinding(DefaultParameterSetName='All')]  
    param(  
        [Parameter(  
            Mandatory = $false,  
            ParameterSetName = 'UPN',  
            Position = 0  
        )]  
        [string[]]  $UserPrincipalName,  
   
        [Parameter(  
            Mandatory = $false,  
            ParameterSetName = 'All'  
        )]  
        [switch]    $All  
    )  
    BEGIN {  
        if (-not (Get-MsolDomain -ErrorAction SilentlyContinue)) {  
            Write-Error "You must connect to the MSolService to continue" -ErrorAction Stop  
        }  
    }  
    PROCESS {  
        if ($PSBoundParameters.ContainsKey('UserPrincipalName')) {  
            $MsolUserList = foreach ($MsolUser in $UserPrincipalName) {  
                try {  
                    Get-MsolUser -UserPrincipalName $MsolUser -ErrorAction Stop  
                       
                } catch {  
                    Write-Error $_.Exception.Message  
                }  
            }  
        } else {  
            $MsolUserList = Get-MsolUser -All -ErrorAction Stop | Where-Object {$_.DisplayName -notmatch 'On-Premises Directory Synchronization'}  
        }  
   
        #Now that we have our UserList, lets check the per-user mfa status  
        foreach ($User in $MsolUserList)   
        {  
        $MethodType = $User.StrongAuthenticationMethods | select -ExpandProperty MethodType  
           if ($User.StrongAuthenticationRequirements)   
           {  
                $PerUserMFAState = $User.StrongAuthenticationRequirements.State  
   
            }   
            else   
        {$PerUserMFAState = 'Disabled'}  
        if ($MethodType -eq 'OneWaySMS')   
        {  
            [PSCustomObject]@{  
                UserPrincipalName    = $User.UserPrincipalName  
                DisplayName          = $User.DisplayName  
                PerUserMFAState      = $PerUserMFAState  
                DefaultMethodType    = 'SMS Text Message'  
            }            
            $MethodType        = $null  
        }}}  
    END {}  
}  
  
 Get-PerUserMFAStatus -All   

Hope that will help you to collect all required information.
