In this article, we are going to generate JWT Access Token to authenticate users against .NET6 Web API application. JWT Token(Or Access Token): JWT Token(JSON Web Token) is a digitally signed and secured token for user validation. JWT Token building components are like: Header Payload Signature JWT Access Token Flow: User request API with user credentials API validates the user credentials and generates the JWT token returns it as a response to the client application. The client application on receiving the JWT token makes the user authenticated and sends the JWT token as a header to every subsequent API request. API reads the JWT token from the request header, then API validates the token if it is a valid token then API allows the request to consume its authorized resources. Create A .NET6 API Project: Let's create a .Net6 Web API sample application to accomplish our demo. We can use either Visual Studio 2022 or Visual Studio Code(using .NET CLI commands) to create any.Net
