Update existing item details to store credentials

Idea created by nadiguy on Dec 20, 2016

    Please add the ability to update existing ArcGIS Online item to store credentials in cases that ArcGIS For Server services are secured after they were registered as items to ArcGIS Online.

    Today their is an option in ArcGIS Online to store credentials only for new items, but no option to update existing items to store service credentials when it become secured after registration.
