The bearer token is the token you'll use for accessing information and services.
User authentication happens according to the IDP’s policies (username and password, one-time password, biometric, etc.), and upon successful authentication, the IDP generates an implicit grant (aka bearer token) or an authorization code grant. As illustrated below, the user is redirected to the IDP web site. When using OAuth, you delegate user authentication to a third-party Identity Provider (IDP). The service that acts as a public-facing identity provider for Amazon is Login with Amazon. These are sites where nearly everyone has an account, such as Facebook, Google, Twitter, and Amazon.
Many organizations rely instead on well-known identity providers, available on the internet. However, at smaller companies, this would require you to build, operate, and maintain your own complex system to manage user identities, passwords, and profiles in a secure and scalable way. At some large companies, an OAuth server is probably already available and Identity Management procedures already in place. The Basics of Account Linking with the Login with Amazon (LWA) ServiceĪccount linking leverages OAuth 2.0 an open protocol that provides a simple, standards-based method for web, mobile and desktop applications to request user authorization from remote servers.Īs a skill developer, you could set up and configure your own OAuth server and identity management system.
