Answer 1

You get following message

You are required to authenticate to complete the action. when you try to upgrade or install the sample data in Magento 2 using Composer method using following command.

php <your Magento install dir>/bin/magento sampledata:deploy

This is a new concept in Magento 2 for upgrades. You have to configure your keys in you Magento account under connect tab secure keys section. (As you have to access a repository)

You will find following excerpt from Magento official documentation :

The repo.magento.com repository, where Magento 2 and third-party component Composer packages are stored, requires authentication. To provide secure authentication, we enable you to generate a pair 32-character authentication tokens you can use to access the repository.
