The default username is: root
And the password is the one that is emailed to you.
The password is case sensitive, so please be sure to enter it exactly as it was emailed.
In the HTML5 console after you enter in the username "root", when you enter in the password it will not be echoed to the terminal, so it will look like nothing is being inputted but that is just because of security.
If you have any other questions please let us know.
