Remove step #6 in the Basic Setup for Project #2

Unless I'm missing something, this step appears to be redundant.  I could create the validations: 'validates :password, confirmation: true' and 'validates :password_confirmation, presence: true' to check that there is a password_confirmation and that it matches the password  However, this is already taken care of by the addition of #has_secure_password in step #5, as seen in the documentation and example here:   https://www.omniref.com/ruby/gems/activemodel/4.1.6/symbols/ActiveModel::SecurePassword::ClassMethods/has_secure_password
Error in the full controller code

Should be 'whitelisted_post_params' instead of 'params[whitelisted_post_params]'
