+Choose the HTTP basic authentication.

+Basic authentication sends a Base64-encoded string that contains a user name and password
+for the client. Base64 is not a form of encryption and should be considered the same as
+sending the user name and password in clear text (Base64 is a reversible encoding).
+If a resource needs to be protected, strongly consider using an authentication scheme
+other than basic authentication. HTTPS/TLS should be used with basic authentication.
+Without these additional security enhancements, basic authentication should not be used
+to protect sensitive or valuable information.
