Support github access tokens

[Tadaboody]

Access tokens Are a necessity for users who have Two-Factor-Authentication enabled. They should be Available to be used instead of a password, perhaps taken from an environment variable automatically

Thanks for the suggestion! I'm completely on board with using 2FA - however, in this particular case, it's not clear where a 2FA token is required. The only repository that is accessed by the beeware tool is the briefcase template, which is a public repository. Where are you seeing issues with 2FA requirements?

It seems I've misunderstood, the username/password arguments for main.py are for what user?

Aargh - my apologies! I misread the repository name where you reported this issue!

You're absolutely right - 2FA handling may be required, depending on how you use/deploy Beefore. It's less significant for Beeware itself; we use a robot user account that doesn't have 2FA enabled. However, other uses may well need 2FA handling.
