You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: authenticatable.rb
    path of file: ./repos/stackneveroverflow/vendor/bundle/ruby/2.3.0/gems/devise-4.3.0/lib/devise/strategies
    
    the code of the file until where you have to start completion: require 'devise/strategies/base'

module Devise
  modu
    
      def parse_authentication_key_values(hash, keys)
        keys.each do |key, enforce|
          value = hash[key].presence
          if value
            self.authentication_hash[key] = value
          else
            return false unless enforce == false
          end
        end
