Question

I am using the ChangePassword web control in order to change the user password. my provider is using hashed password, and I am want to keep using it.
just wanted to know if there is a way to compare the current password the user entered with the old password in the DB.

Answer 1

You can use Membership.ValidateUser method, that returns true or false, depending on whether the entered password – in your case the new password – is the same as the old password.
