Entrance to your account is protected with both a Username and a Password which you received in your confirmation email after you opened your account. Unless otherwise indicated, your Username will be your domain name without an extension. For example, "yourdomain" rather than "yourdomain.com"
Please note that your Password and Username are not interchangeable. Also,
confusion can sometimes arise when different programs use different terms
to indicate Username. For example, SSH uses the term "login" instead
of Username. As a rule, the term Password is standard and used consistently
from program to program. If something else is called for, such as User ID,
or Login, enter your Username.
