ASP.Net Core Web API JWT Tutorial [Using JWT in ASP.Net Core]

🚀 Let's explore how to implement JWT authentication in an ASP.NET Core Web API

In this ASP.Net Core Web API JWT Tutorial video, we will explore how to implement JWT authentication in an ASP.NET Core Web API, providing a comprehensive understanding of JWT tokens and their usage in web applications [Using JWT in ASP.Net Core].

What is JWT?
JSON Web Token (JWT) is a compact, URL-safe means of representing claims to be transferred between two parties. The claims in a JWT are encoded as a JSON object and are typically used for securely transmitting information between a client and a server.

Why Use JWT?
JWT tokens are widely used for authentication purposes in modern web applications. They offer several advantages:
1. Stateless Authentication: Unlike traditional session-based authentication, JWTs are stateless, meaning the server does not need to store session data. This improves scalability and performance.
2. Security: JWTs are signed using a secret key or a public/private key pair, ensuring the integrity and authenticity of the token.
3. Cross-Domain Support: JWTs can be used across different domains and services, making them ideal for microservices and distributed systems.

When to Use JWT?
JWTs are suitable for scenarios where you need a stateless and secure way to authenticate users. Common use cases include:
1. API Authentication: Using JWTs in ASP.NET Core Web API for authentication and authorization.
2. Single Sign-On (SSO): Implementing SSO across multiple applications and domains.
Mobile and SPA Applications: Authenticating users in mobile apps and single-page applications.

Advantages of Using JWT:
1. Performance: JWTs eliminate the need for server-side session storage, enhancing performance and scalability.
2. Flexibility: They can carry any type of claim, allowing for easy extensibility.
3. Interoperability: JWTs are platform-independent and can be used in various programming environments.
4. By understanding the fundamentals of JWT and its benefits, you'll be better equipped to implement JWT authentication in your ASP.NET Core Web API projects, ensuring secure and efficient authentication and authorization processes.

Great video, Thank you so much. I followed everything and jwt authorizing worked well, but unfortunately the token is not getting expired after the desired time. what may be the reason?
