public class PasswordQuestion
extends TextQuestion

A password entry box where the password shows up as "****" instead of text. If you use it like this:
<%@ taglib uri="/WEB-INF/SurveyTags.tld" prefix="survey" %>.
<survey:survey databaseName="<%=databaseName%>" table="tbladmin" >.
<%survey:passwordQuestion question="Password" dbField="passwordField"/>.
</survey:survey>.
It will show up in the page looking like this:

Password

PasswordQuestions can only be used on fields in the database where the field is of type "string" and the choices you have for the type are "string", "stringKey", "password" or "passwordKey". (For internal security purposes, the "string" and "stringKey" labels are changed to "password" and "passwordKey" -- this is how the server identifies it as a password and checks the value coming in from the client to make sure it's not the default value -- see below as to why this is more secure).

Note: The password is secure only when using a secure certificate and https. The password will not be passed back from the server to the user computer -- instead, it puts in the contents of DefaultPasswordValue, so that a user examining someone else's password page can change it but not see what it is. This also prevents snooping on outgoing server packets from getting passwords.

Note: a good future security feature would be to encrypt these passwords in the database. That change would also need to be made in Survey, which does the comparison to make sure the password is right when the user is entering it to get into the site.
