Authentication required (repo.magento.com):

When we attempt to install magento for the first time, we will be prompted to enter a username and password; if we dig around a bit more, we will learn that this is actually not what people would intuitively expect a username and password to be — instead, this actually refers to a public and private key pair that you must first generate.

Before you can install magento using composer, you first need to generate this key pair; to do that, complete the following steps:

1. Create an account at magento.com, and agree for them to send you marketing e-mails (spam?).
2. Validate your e-mail address. Note that you might not get the first validation e-mail, so you may need to request a second one!
3. Login on https://marketplace.magento.com/
4. Create a new access key. This generates a public and a private key; the public key is your username, and the private key is your password.

After doing this, simply enter the command from terminal to install magento:

composer create-project --repository-url=https://repo.magento.com/ magento/project-community-edition /path/to/install/directory
