ArcGIS supports secure access to ArcGIS services and portal items. It ensures that only valid, authorized users and services can access protected information. To access secure ArcGIS resources, you need an access token that you can obtain by implementing an authentication workflow in your app. The type of authentication you use depends on the security and access requirements of your app.
