No more specific user login credentials! Developers will definitely appreciate this announcement by Amazon that their apps and games that use Login with Amazon on Kindle Fire devices will no longer need to ask users to sign in each time the app is run.
Instead, the first time the app is run Login with Amazon will automatically use the account registered to the Kindle Fire device. The user will then simply need to consent to share their information once for each of those apps to be automatically signed in.
In addition to enabling single sign-on for Kindle Fire, Login with Amazon is now integrated with the Amazon Mobile App SDK with documentation available in the API section of the Amazon developer portal. So developers whose apps have implemented Login with Amazon will no longer need to ask customers to sign in each time. All third generation of Kindle Fire devices support the new login.
To enable Login with Amazon, developers will click on the Login with Amazon tab in the developer console to create or select a security profile. Next, follow the steps provided to setup the developer environment and add Login with Amazon to the app.
