Q:

Azure Mobile App Service

I would like to create a mobile app with Xamarin Forms and would like to use the new Azure Mobile App PaaS service.  This mobile app shall be available also to users which uses my services from a web site and not only from a mobile device. 
In regards to Authentication how can I have a single authentication point available either from a web site as well as from the mobile app? 
Does anyone have suggestions on how to design this architecture? 

A:

The Azure App Service, the Mobile Apps backend service is really just a Web API running in Web Apps (think web site + mobile goodness), with all features of App Service sharing the same authentication endpoint.  This means that any authentication you setup for mobile device clients can also be used by a web site.
