You can't call validates_confirmation_of in the module itself because the module's code is executed when it is created. Instead, you want to call the validation method when the module is included in the ActiveRecord model, like so:

module Password::ClassMethods
  def self.included(base)
    base.send(:validates_confirmation_of, :password)
  end
end
