If you haven't yet created an account, you can do so from the interactive installer's Login Menu.
At your device's console, run:
Select option 2 to create a new account.
You will receive a verification e-mail within a few minutes. In rare cases these can wind up in your spam folder, so check there if you don't receive an e-mail in your inbox within 5 minutes.
Once you receive the verification e-mail with the code, choose option 3 to enter the verification code. You will also enter and confirm your password during this step.
