Basic authentication in ASP.NET Core
Basic authentication is used in a HTTP request by adding a Base64 encoded username and password to the Authorization header.
It is used in OAuth as part of the client credentials flow for requesting an access token in the form of a Bearer token.
What's included?
The code sample will give you the functionality to add Basic authentication into an ASP.NET Core Web API.
This includes the authorize attribute, client identity and the authentication handler. In-addition, a controller has been set up to use Basic authentication along with configuration in Swagger. This means that it can tested when running the web app.
Watch our video to see what files are included, how we implemented the functionality and how we tested it.
In addition, you can read more about Basic authentication so you get a better understanding of how it can be used as part of the OAuth Client Credentials grant type.
