In this meeting, the State Changers discuss the authentication process for their project. They mention using Xano, Auth0, and Kakao for authentication, and they want to enable federated sign-in using Kakao credentials. They discuss the redirect URI and how it is used in the authentication flow. They also talk about the security concerns and how to prevent unauthorized access. They set up an API endpoint in Xano to handle the authentication process and discuss how to retrieve and store the ID token for authentication. They plan to test the authentication flow and issue an authorization token once the user is authenticated.
