If your application connects to an application on a server or to the Internet or an intranet, you might want to include additional authentication features when the BlackBerry® device users log into the server. Most applications that require user authentication rely on HTTP Basic authentication, which uses a simple user name and password combination. You can use HTTP Basic authentication by adding the correct HTTP headers while opening the HTTP connection. You can also add more advanced authentication using certificates; however, most applications do not require it.
