-> This is the second chapter of the first phase of this ASP.NET Core Web App tutorial. Once you understand how to sign-in users in an ASP.NET Core Web App with Open Id Connect, can learn how to enable your [Web App to call a Web API on behalf of the signed-in user](../../2-WebApp-graph-user) in a later chapter.

 #### Sign-in
 
-Users can only sign-in if their tenant had been onboarded. The sample will guide them for it, but it requires a **tenant admin account** to complete the onboarding process. Once the admin have consented, all users from their tenant will be able to sign-in.

 #### Todo List
 
-Users from one tenant can't see todo items from another tenant. They will be able to perform basic CRUD operations on todo items assigned to them. When editing a todo item, users can assign it to any other user from their tenant.
