I am trying to use Azure AD B2C to authenticate users of an Angular2 single-page app. I understand I can use the UI (either default or customized) that is associated with each Azure AD B2C policy. For a number of reasons I am not happy with the Azure AD B2C UI (or the effort required to customize it).
Therefore I'd like to use my own UI within my app that would just make calls to Azure AD B2C. Is that possible? If so, how? I have looked at Azure AD B2C Custom Policies, but I an not sure if those still use the default (or customized) Azure AD B2C UI.
