Configuring Create User Form Fields

The following web configuration file makes both an email address and security question and answer optional.
File: Web.Config
<configuration>
  <system.web>
    <authentication mode="Forms" />
    <membership defaultProvider="MyMembership">
      <providers>
        <add
          name="MyMembership"
          type="System.Web.Security.SqlMembershipProvider"
          connectionStringName="LocalSqlServer"
          requiresQuestionAndAnswer="false"
          requiresUniqueEmail="false" />
      </providers>
    </membership>
  </system.web>
</configuration>
If you add the web configuration file to your application, then the CreateUserWizard control does not render fields for a security question and answer.


Requiring a Security Question and Answer

File: Web.Config
<configuration>
  <system.web>
    <authentication mode="Forms" />
    <membership defaultProvider="MyMembership">
      <providers>
        <add
          name="MyMembership"
          type="System.Web.Security.SqlMembershipProvider"
          connectionStringName="LocalSqlServer"
          requiresQuestionAndAnswer="false"
          />
      </providers>
    </membership>
  </system.web>
</configuration>


Sending the Original Password

File: Web.Config
<configuration>
  <system.web>
    <authentication mode="Forms" />
    <membership defaultProvider="MyMembership">
      <providers>
        <add
          name="MyMembership"
          type="System.Web.Security.SqlMembershipProvider"
          connectionStringName="LocalSqlServer"
          passwordFormat="Clear"
          enablePasswordRetrieval="true"
          />
      </providers>
    </membership>
  </system.web>
</configuration>
