I have some Experiences I've created using Dev Ed 1.13, and would like to make a limited amount of data available to end users via the add data widget through a curated group. I'm wondering if it's possible to encode credentials (this would be for a viewer account with limited permissions) into the app to allow for automatic authentication so that the resources in the curated group would not have to be set to public and users would not have to log in to AGOL.
A few notes: I have CORS restrictions set and am serving the apps through WP shortcodes to allow them to be placed behind a login.
