I am trying to configure my access to GitHub and no matter what I do I get the "Authentication failed" message. I have tried everything I know to try. I have even disabled two-factor authentication and just tried using a username and password which I know is correct. I simply want to make it work so that I can set a bot with OS X Server.
Is there a guide somewhere which helps with troubleshooting access problems with Xcode repository configurations and GitHub. It appears to be completely non-functional.
