ASP.NET Core Web API Authentication with Identity 🔐

🔐 ASP.NET Core Web API Authentication with Identity (Register, Login, Change Password)

In this video, you’ll learn how to build a simple and complete authentication system using ASP.NET Core Web API with ASP.NET Core Identity.

We walk step by step through creating authentication APIs for user registration, login, and password changes, and we test everything using Swagger UI. This tutorial is perfect if you want to understand how Identity works behind the scenes in a real Web API project.

🚀 What you’ll learn in this tutorial:

Create a new ASP.NET Core Web API project in Visual Studio

Install and configure Entity Framework Core, ASP.NET Core Identity, and Swagger

Set up SQL Server and connection strings in appsettings.json

Create a custom ApplicationUser by extending IdentityUser

Configure ApplicationDbContext using IdentityDbContext

Configure ASP.NET Core Identity in Program.cs

Apply Entity Framework migrations to generate Identity tables

Build request models for Register, Login, and Change Password

Implement authentication logic using UserManager and SignInManager

Fix common Identity configuration issues

Configure cookie-based authentication for Web API

Customize authentication responses (401 & 403 instead of redirects)

Test all authentication APIs using Swagger UI

By the end of this video, you’ll have a fully working authentication system built with ASP.NET Core Identity, and you’ll understand how to properly configure authentication middleware for Web APIs.

If you’re building REST APIs, learning backend authentication, or preparing for real-world ASP.NET Core projects, this video will help you a lot.
