Does anyone know how to use AWS Cognito handle user registration and sign in for a mobile app? I have been trying to find examples/tutorials online for a while now but can't seem to find anything that will fit what I am looking for.
I have been following this guide but it doesn't seem to have anything to handle the sign in and sign up:
http://docs.aws.amazon.com/mobile/sdkforxamarin/developerguide/getting-started-xamarin.html
In my search I found that you can access CognitoUserPool in a PCL by adding the Amazon.Extensions.CognitoAuthentication Nuget package which is used in this tutorial for android:
http://docs.aws.amazon.com/cognito/latest/developerguide/using-amazon-cognito-user-identity-pools-android-sdk.html#using-amazon-cognito-user-identity-pools-android-sdk-register
I have also looked at the Xamarin example provided (https://github.com/xamarin/xamarin-forms-samples/tree/master/WebServices/TodoAWSAuth) but that is using Google as an authentication provider. I need to be able to have a custom login/sign up page.
