Let me show you how to edit value of RequiresQuestionAndAnswer in ASP.NET 4.6 Membership provider. RequiresQuestionAndAnswer is checked when ResetPassword or GetPassword is called. The provider provided with the .NET Framework throws a NotSupportedException if RequiresQuestionAndAnswer is true and the supplied password answer is null. Requiring a password question and answer provides an additional layer of security when retrieving or resetting a user's password. Users can supply a question and answer when their user name is created that they can later use to retrieve or reset a forgotten password.

A Membership Provider allows a web application to store and retrieve membership data for a user, and the standard ASP.NET Membership Provider uses pre-defined SQL Server tables.

Now you write the following example code:
MembershipUser user = Membership.GetUser();
string newPassword = "newPass";
string tempPassword = string.Empty;
if (Membership.Provider.RequiresQuestionAndAnswer)
var _requiresQA = Membership.Provider.GetType().GetField("_RequiresQuestionAndAnswer",
System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
//change the value in the private field
_requiresQA.SetValue(Membership.Provider, false);
//do the reset
tempPassword = user.ResetPassword();
//set it's original value
_requiresQA.SetValue(Membership.Provider, true);
tempPassword = user.ResetPassword();
