I am looking a building an application for my enterprise users who have an Azure Active Directory account. The concept is still on the drawing board but we are looking to potentially have features available in the native app and features that are already build within a responsive web view. All features both native and in the web view are secure and the user must be authenticated to access the content. Can I create my own ViewController to allow user to input Username and password to authenticate against AAD? Once authenticated can I also pass the security token to the web view so the web view knows the user is logged in and does not have to re authenticate to view pieces of content in the web view?
