+### Authentification avec ASP.Net Identity Core
+
+```console
+$ cd Infrastructure
+$ dotnet add package Microsoft.AspNetCore.Identity.EntityFrameworkCore
+```
+
+On fait hériter notre `HNDbContext` de `IdentityDbContext`. On peut créer des types customs pour nos User et Role de manière à utiliser des Guid et rester cohérent.
+
+Côté web, on s'assure d'avoir bien ajouter `AddIdentity` avec les options qui nous intéressent.
+
+Grâce à ça, nous aurons à notre disposition un `UserManager<User>` et un `SignInManager<User>` nous permettant de réaliser les opérations d'authentification. Bien penser au `UseAuthentication` avant le `UseAuthorization` afin que l'authentification puisse avoir lieu.
+
 ## Démarche
 
 On crée un fichier solution avec `dotnet new sln`. On pourra alimenter ce fichier sln avec la commande `dotnet sln add DirProjet`.
