Get MFAStatus with API

Hi,

 

I'm trying to get a report for the MFA status for all my tenant users.

# Replace the values in the following variables with your own
$clientId = "your_client_id_here"
$clientSecret = "your_client_secret_here"
$tenantId = "your_tenant_id_here"

# Authenticate using Microsoft Graph API
$tokenBody = @{
    Grant_Type    = "client_credentials"
    Scope         = "https://graph.microsoft.com/.default"
    Client_Id     = $clientId
    Client_Secret = $clientSecret
}
$tokenResponse = Invoke-RestMethod -Method POST -Uri "https://login.microsoftonline.com/$tenantId/oauth2/v2.0/token" -Body $tokenBody
$accessToken = $tokenResponse.access_token

# Retrieve all users in the tenant
$users = Invoke-RestMethod -Method GET -Uri "https://graph.microsoft.com/v1.0/users" -Headers @{Authorization = "Bearer $accessToken"}

# Loop through each user and retrieve their MFA status
foreach ($user in $users.value) {
    $userId = $user.id
    $mfaStatus = Invoke-RestMethod -Method GET -Uri "https://graph.microsoft.com/v1.0/users/$userId/authentication/strongAuthenticationMethods" -Headers @{Authorization = "Bearer $accessToken"}
    $mfaEnabled = $mfaStatus.value | Where-Object {$_.state -eq "enabled"}

    Write-Output "$($user.displayName) - MFA Enabled: $($mfaEnabled -ne $null)"
}

 

I got this script but I'm always getting an error when I'm trying to execute it ... error is : 

Line |
  17 |  $users = Invoke-RestMethod -Method GET -Uri "https://graph.microsoft. …
     |           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     | {"error":{"code":"Authorization_RequestDenied","message":"Insufficient privileges to complete the
     | operation.","innerError":{"date":"2023-03-28T00:21:46","request-id":"d929a2d8-ca16-44b4-af0b-4d514c15ea78","client-request-id":"d929a2d8-ca16-44b4-af0b-4d514c15ea78"}}}

 

In my API permission, I've double check to be sur all permission are ok :

  • UserAuthenticationMethod.Read.All or UserAuthenticationMethod.ReadWrite.All (for Microsoft Graph API v1.0) OR AuthenticationMethod.Read.All or AuthenticationMethod.ReadWrite.All (for Microsoft Graph API beta)
  • User.Read.All or User.ReadWrite.All (for Microsoft Graph API v1.0) OR Directory.Read.All or Directory.ReadWrite.All (for Microsoft Graph API beta)

I've check again my clientID-clientSecret-TenanID and seems to be good : How to be sure this is OK? Any log in AzureAD to check if at least my script is able to authenticate?

 

Thanks in advance!

    Not sure where you got this code, but there is no /users/$userId/authentication/strongAuthenticationMethods endpoint. The correct one should be /users/$userId/authentication/Methods, or if you are looking for the report instead, /reports/credentialUserRegistrationDetails.

    The token part looks fine, but make sure the permissions are correctly reflected in the obtained access token. You can parse it with tools such as jwt.ms.

      To be honnest, this code is from ChatGPT! 🙂 You understand that I'm not a professionnal in powershell!! 🙂

      I tried you modification and same error at same line .... like if I have an authorization problem.

      Can you give me a cue to check if my authentication and permission are good with the API?

      THanks

        ChatCPT is smoking something good, again... 🙂

        Let's start with the basics, did you create an app registration and grant the permissions? In other words, are you populating the variables with the correct values?

        $clientId = "your_client_id_here"
        $clientSecret = "your_client_secret_here"
        $tenantId = "your_tenant_id_here"

        Double- and triple-check if everything is OK there. Once you run the following:

        $accessToken = $tokenResponse.access_token

        you can do another check - decode the token and make sure the required permissions are correctly reflected therein. To do so, copy the token and head over to https://jwt.ms to decode it. You can copy it directly via:

        $accessToken | clip
