How does JWT authentication work in ASP.NET Core?

JWT (JSON Web Token) authentication in ASP.NET Core allows you to securely transmit information between parties as a JSON object. It is compact, URL-safe, and can be verified and trusted because it is digitally signed.

What are the benefits of using JWT over traditional session-based authentication?

JWTs are stateless, meaning they don't require server-side storage, which makes them scalable. They also allow for cross-domain authentication and can be easily used in mobile applications.

Can you explain how to implement JWT authentication in an ASP.NET Core application?

Sure! First, you need to install the necessary NuGet packages, then configure the JWT authentication in the Startup.cs file, and finally, create a token generation method.

What are some common security practices when using JWT?

Common practices include using HTTPS, setting short expiration times for tokens, and implementing token revocation strategies.
