How can I use AWS-Cognito for user authentication in a web app (not IOS or Android app)?
Amazon cognito just came out:
http://aws.amazon.com/cognito/
http://aws.amazon.com/about-aws/whats-new/2014/07/10/introducing-amazon-cognito/
From the FAQ:
Q: Do I still need my own backend authentication and identity systems with Amazon Cognito?
No. Amazon Cognito supports login through Amazon, Facebook and Google, as well as providing support for unauthenticated users. With Amazon Cognito you can support federated authentication, profile data sync store and AWS access token distribution without writing any backend code.
It seems to be built with mobile apps in mind (they provide SDKs for android and IOS).
So far the AWS php SDK and boto don't reference Cognito, but Amazon mentions "back-end API's" that we can hit.

You can use Amazon Cognito to control permissions for different user groups in your app. This ensures that users have appropriate access to backend resources, determined by the group they belong to. Amazon Cognito makes it easier for you to manage user identities, authentication, and permissions.
Amazon Cognito enables simple, secure user authentication, authorization and user management for web and mobile apps. With Cognito, a user or visitor can sign in with a username and password through Amazon, or through a third party like Facebook, Google or Apple.

Additionally, a number of the AWS SDKs have already been updated to support Amazon Cognito:
With more coming soon.

Cognito is perfect for web apps. There is a good tutorial on using Cognito ID and Sync for Javascript web apps: http://backspace.technology/learn-aws-cognito.html and at http://blog.backspace.academy/2015/03/using-cognito-with-node.html
Update: There is now a Cordova/PhoneGap tutorial also at http://backspace.technology/learn-aws-cognito-id-phonegap.html and at http://blog.backspace.academy/2015/03/using-cognito-with-phonegapcordova-part.html
The process is as follows:
Although if you are only looking for authentication then you don't actually need Cognito, you just login with Facebook.

From what I see in their FAQ, yes:
Q: Does Amazon Cognito expose server-side APIs?
Yes. Amazon Cognito exposes server-side APIs. You can create your own custom interface to Amazon Cognito by calling these APIs directly. The server-side APIs are described in the Developer Guide.
