Peter, My colleague, Will Boyd is the Training Architect for that course and I believe the labs pull from Github, but since the spin up of the lab (AWS AMI File) is doing it, you may not need your own credential. I have a github account, which is free BTW, so I have no way to know what happens without it. Perhaps Will willl respond here, but I would say just try it, and see if it works. Again, you can set up a free account if you actually need authentication. Good luck - John.
