can a group of people (let say 100 people) share one AGOL VIEWER account login (same user name and password) and access a private web app within the organization? if so, can they view the app at the same time invidually?
Sharing a username and password so multiple users are using the same username and password is a violation of the licensing Agreement (section 2.5).
I'd suggest getting in contact with Esri Customer Service or your account rep to look at the licensing options available.
