ASP.NET Core Identity
ASP.NET Core Identity is an extensible ASP.NET Core membership system for managing user accounts, credentials, claims, roles, authentication, and related identity data.
ASP.NET Core in Action, 3e
ASP.NET Core Identity is an ASP.NET Core membership system that provides user accounts, authentication, authorization integration, and related identity-management services.
- How it is used
- Provides user accounts and sign-in for ASP.NET Core applications, leaving access-control decisions to authorization.
- How deep it goes
- Works through cookie sign-in, generated UI, EF Core storage, integration steps, and custom claims; defers detailed API authentication and authorization.
- Examples
- Uses an Individual Accounts template, an existing recipe application, and a registration-page FullName claim.
- What you can do after
- Apply it via ASP.NET Core Identity to add registration and login, extend an EF Core app, and customize a registration claim.

Building Web APIs with ASP.NET Core
ASP.NET Core Identity is an ASP.NET Core framework subsystem that provides abstractions and components for managing user accounts, authentication, and related identity data.
- How it is used
- Supplies user-account management for securing data-changing endpoints in a board-game API.
- How deep it goes
- Walks through packages, entities, migrations, and service configuration, but defers an exhaustive account of IdentityUser properties.
- Examples
- Uses a board-game API, an IdentityUser-derived entity, database migrations, and Program.cs service configuration.
- What you can do after
- Build it from scratch: configure Identity-backed accounts and JWT bearer authentication as the foundation for protected API endpoints.

Pro ASP.NET Core 7, Tenth Edition
ASP.NET Core Identity is an extensible membership system for managing users, credentials, claims, roles, and related authentication functionality in ASP.NET Core applications.
- How it is used
- Secures restricted application features by managing users and integrating authentication and authorization into the request pipeline.
- How deep it goes
- Works through database setup, account and role management, sign-in, and authorization; leaves Identity’s wider integration options unexplored.
- Examples
- Uses a protected administration area, an Identity database context, account-management tools, and an authenticated-user details page.
- What you can do after
- Build it from scratch: configure database-backed Identity, manage accounts and roles, authenticate users, and restrict access.

.NET in Action, Second Edition
ASP.NET Core Identity is an extensible membership system for managing users, authentication, authorization, and related identity data in ASP.NET Core applications.
- How it is used
- Protects ASP.NET Core APIs by authenticating requests and authorizing access to endpoints.
- How deep it goes
- Shows JWT bearer registration, middleware ordering, and controller protection, while deferring broader Identity account management.
- Examples
- Uses JWT bearer configuration and an Authorize-protected CatalogController.
- What you can do after
- Operate/configure ASP.NET Core Identity to authenticate JWT requests and protect API controllers.
