How to Change Password ASP.Net without entering old password

The concept is to use one provider for password reset and one provider for every other function in your site.
And the code becomes like this:

Vb.Net Code:

        Dim user As MembershipUser
        user = Membership.GetUser(username)
        Dim oldpass As String = user.ResetPassword
        user.ChangePassword(oldpass, newpassword)

C# Code:

MembershipUser user = Membership.GetUser(username);
string oldpass = user.ResetPassword;
user.ChangePassword(oldpass, newpassword);

Hope you find it useful!
