I have a big CSOM powershell script which is using basic authentication. This script is scheduled to run every day. This script is using credentials of a serviceaccount without MFA. We would like to disable basic authentication, but this script needs to be modified. I dont want to rewrite the whole CSOM script to Office Dev PnP Powershell because it is a big script.
What is the easiest way to move from basic to modern authentication in a CSOM powershell script?
See below a small part with authentication and some SPO logic:
$lo_ClientContext = New-Object Microsoft.SharePoint.Client.ClientContext( https://myCompany.sharepoint.com/sites/test )
$lo_ClientContext.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials( Email address removed, myPassword )
$lo_ClientContext.ExecuteQuery()
$ll_Lijst = $lo_ClientContext.Web.Lists.GetByTitle( "myList" )
$lo_ClientContext.Load( $ll_Lijst )
$lo_ClientContext.ExecuteQuery()
