HTTP Basic Authentication is a simple and widely used method to secure web resources. In this mechanism, the client (such as a browser or an API client) sends a username and password to the server for each request. The credentials are encoded in Base64 and included in the "Authorization" header.

Here's how it works:

The server requests authentication by sending a 401 Unauthorized response, prompting the client to provide credentials.

The client responds with the "Authorization" header, which includes the credentials encoded as Base64 (e.g., Authorization: Basic ).

The server decodes the credentials, verifies them, and grants access if they are correct.

Since Base64 is a reversible encoding, HTTP Basic Authentication is not secure by itself. It should always be used over HTTPS to encrypt the connection and protect credentials from being intercepted during transmission.
