After working on something similar to this, I settled on using Application Controller, then afterward found that the Devise Documentation is fairly straightforward for this in their strong parameters section and gives an alternative to using Application Controller. https://github.com/plataformatec/devise#strong-parameters

Below is the approach with Application Controller which worked for me.

    class ApplicationController < ActionController::Base

      before_filter :configure_permitted_parameters, if: :devise_controller?

      private

      def configure_permitted_parameters
         devise_parameter_sanitizer.for(:sign_up){ |u| u.permit(:name, :username, :about,  :email, :password, :password_confirmation)}        
         devise_parameter_sanitizer.for(:account_update){ |u| u.permit(:name, :username, :about, :email, :password, :password_confirmation) }          
      end

    end

This should work the same and it directly overwrites methods in Devise::RegistrationController.

    class Users::RegistrationsController < Devise::RegistrationsController

      private

      def configure_sign_up_params
        devise_parameter_sanitizer.for(:sign_up){ |u| u.permit(:name, :username, :about,  :email, :password, :password_confirmation)}
      end

      def configure_account_update_params
        devise_parameter_sanitizer.for(:account_update){ |u| u.permit(:name, :username, :about, :email, :password, :password_confirmation) }
      end

    end
