Once the network configuration is complete you are given the opportunity to add a new user during the installation process. This new user will be an administrative user, they will be part of the 'admin' group and an SSH key will be automatically created for the user.
If you chose to create a new user at this point, you will need to enter in the users real name, user name, and a password. Once all required fields have been entered hit Ok to create the account.
