Running an app on Azure and protecting signups

Question

I'm about to finish an app that will run on Windows Phone and Android. It uses an azure web API and push notification service.

I was wondering if there is any standard or recommended way of protecting the 'signup' or 'register' functionality within an app like this? I note that some popular apps like snapchat will send you a text to verify the registration process. That would be ideal but obviously seems unfeasible for a modest app such as mine :-)

Can anyone enlighten me to some common ways to protect the 'register' functionality of a mobile app?

Thanks for any help!

Azure provides feature sets like Azure Mobile Services that provide authentication features that you can use in your Windows Phone apps. I doubt the authentication Azure Mobile Services uses is restricted to just Azure Mobile Services, but more information on getting started with this authentication can be found here: http://azure.microsoft.com/en-us/develop/mobile/resources-wp8/#header-2
