Tutorial: User Auth with Stream Chat & Feeds

Integrating Stream for user authentication in applications involves generating a user token server-side, which is necessary for initializing Stream's SDK in both web and mobile environments. This tutorial focuses on client-side authentication using component-based libraries like React and React Native, while noting that Stream also supports server-side authentication with just an application's key and secret. Stream does not handle user signup or login directly but integrates with existing authentication solutions such as Auth0 or Okta. The process involves having the login or signup API endpoints return Stream's user token along with the session ID, allowing the client-side to use the token to initialize UI components. The tutorial provides code snippets for generating and using the Stream user token, emphasizing the simplicity of the process and directing users to Stream's documentation for more in-depth information.
