Amazon have implemented their OAuth 2.0 protocol Login with Amazon (LWA), which was announced last year, on the Kindle fire, bringing single sign-on for Amazon customers.

 Starting today, mobile apps and games that use Login with Amazon on these Kindle Fire devices will no longer need to ask Amazon customers 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.

Apps that have been granted single sign-on permissions will be able to go into their account online via ‘Your Account’ -> ‘Manage Login’ to see those apps.

All third generation of Kindle Fire are supported including:

For developers to implement single sign-on for their apps, you’ll need to setup your development environment by following the steps below:

  1. Install the Login with Amazon SDK for Android
  2. Run the Sample App
  3. Register with Login with Amazon
  4. Create a Login with Amazon Project
  5. Use the SDK for Android APIs
