Java Servlet Login and Display

Most web apps start with system Login and data Display.

A user can log in to this simple web application using username/password credential or through a third-party authentication provider such as idQ Trust as a Service (idQ TaaS) or Google Identity Platform via OAuth 2.0 protocol.
