java.lang.Objectjavax.mail.Authenticator
The class Authenticator represents an object that knows how to obtain authentication for a network connection. Usually, it will do this by prompting the user for information.
Applications use this class by creating a subclass, and registering an instance of that subclass with the session when it is created. When authentication is required, the system will invoke a method on the subclass (like getPasswordAuthentication). The subclass's method can query about the authentication being requested with a number of inherited methods (getRequestingXXX()), and form an appropriate message for the user.
All methods that request authentication have a default implementation that fails.

Note that if this method uses a dialog to prompt the user for this information, the dialog needs to block until the user supplies the information. This method can not simply return after showing the dialog.
