Basic Header Authentication is a simple method of authentication that doesn't require client-side code and was added to the HTTP 1.0 specification in 1996.
It involves the server sending a 401 Unauthorized status with an authentication header to which the browser automatically prompts the user for their username and password.
Basic Header Authentication is chosen for its simplicity, lack of client-side code requirement, and suitability for small use cases where high-level security is not essential.
Freshers and junior developers should know about Basic Header Authentication as it can be useful for small projects and internal tools, saving time and avoiding the need for frontend login logic.
