A way to set up user-based authentication/authorization for View SDK pdf preview for sensitive PDFs?
So I'm currently building a website that uses View SDK to preview PDFs in-line.
Some of these PDFs contain sensitive information though and I've password-protected them at the file level.
This works as expected. But I've noticed that if I navigate away from the file (load the "adobe-dc-view" div with another PDF) and then return to password-protected file later, I'll be prompted for the password again. Eg.

I am wondering if there's a way for the Adobe View Previewer to somehow "remember" that credentials have already been provided? That way, once the user gives the password once, s/he never needs to do so again.
Furthermore-- What are my options in the Adobe ecosystem if I'm interested in setting up my website so a user can login once and then view all PDFs that s/he is authorized to view? In other words-- I don't want to apply password protection at the file-level. Instead, I want to set up some sort of "sitewide, organization-authentication/authorization" scheme.
Can you please point me in the right direciton? What are my options in the Adobe ecosystem?
