MSAL.PS

The MSAL.PS PowerShell module wraps MSAL.NET functionality into PowerShell-friendly cmdlets and is not supported by Microsoft. Microsoft support does not extend beyond the underlying MSAL.NET library. MSAL.NET (Microsoft.Identity.Client) is an authentication library which enables you to acquire tokens from Azure AD, to access protected Web APIs (Microsoft APIs or applications registered with Azure Active Directory).

Public Client Example

$MsalToken = Get-MsalToken -ClientId '00000000-0000-0000-0000-000000000000' -Scope 'https://graph.microsoft.com/User.Read'
Invoke-RestMethod -Method Get -Uri 'https://graph.microsoft.com/v1.0/me' -Headers @{ Authorization = $MsalToken.CreateAuthorizationHeader() }

Confidential Client Example (aka Client Credential Flow) using a Certificate:

This example assumes the application has been granted relevant application permissions to obtain data from the endpoint defined in <MSGraphEndpoint>.

$ClientCertificate = Get-Item Cert:\CurrentUser\My\0000000000000000000000000000000000000000
$MsalClientApplication = Get-MsalClientApplication -ClientId '00000000-0000-0000-0000-000000000000' -ClientCertificate $ClientCertificate -TenantId '00000000-0000-0000-0000-000000000000'
$MsalToken = $MsalClientApplication | Get-MsalToken -Scope 'https://graph.microsoft.com/.default'
Invoke-RestMethod -Method Get -Uri 'https://graph.microsoft.com/v1.0/<MSGraphEndpoint>' -Headers @{Authorization = $MsalToken.CreateAuthorizationHeader() }

A client secret may be used by Get-MsalToken instead of a certificate, by constructing an object like so: $ClientSecret = 'SECRETVALUEHERE' | ConvertTo-SecureString -AsPlainText -Force and passing this to -ClientSecret rather than -ClientCertificate.
