Amazon has introduced a new 'Login With Amazon' API for web, Android and iOS apps, competing with other OAuth services from Google, Facebook, Twitter and others.
The Login With Amazon platform allows iOS developers to integrate Amazon login to their apps, though developers on other platforms can use other Amazon services to facilitate in-app purchasing over Amazon's platform.
Today, Amazon launched Login with Amazon, a new service that will enable the over 200 million active Amazon customers to securely and simply login to apps, games, and websites. Login with Amazon allows developers to easily reduce sign-in friction for their customers, leading to higher engagement and order conversion.
Login with Amazon is available at no charge to developers of apps, games, and websites. The service is easy to integrate, as developers can typically go from registration to launch in a matter of hours. It is based on the OAuth 2.0 authorization framework, allowing developers to leverage a widely-adopted open protocol.
