How does HTTP Basic Auth work?

HTTP basic authentication is a simple challenge and response mechanism with which a server can request authentication information (a user ID and password) from a client. The client passes the authentication information to the server in an Authorization header. The authentication information is in base-64 encoding.

Considering this, what is HTTP basic authentication and how it works in rest?

In the context of a HTTP transaction, basic access authentication is a method for an HTTP user agent to provide a user name and password when making a request. Rather, HTTP Basic authentication uses static, standard HTTP headers which means that no handshakes have to be done in anticipation.

Subsequently, question is, how do you use basic authentication? To send an authenticated request, go to the Authorization tab below the address bar:

1. Now select Basic Auth from the drop-down menu.
2. After updating the authentication option, you will see a change in the Headers tab, and it now includes a header field containing the encoded username and password string:

Furthermore, is HTTP Basic Auth secure?

The only difference that Basic-Auth makes is that username/password is passed in the request headers instead of the request body (GET/POST). As such, using basic-auth+https is no less or more secure than a form based authentication over HTTPS. Basic Auth over HTTPS is good, but it's not completely safe.

How do I authenticate HTTP request?

A client that wants to authenticate itself with a server can then do so by including an Authorization request header field with the credentials. Usually a client will present a password prompt to the user and will then issue the request including the correct Authorization header.
