Add two factors authentication

[PierrickGT]

I've successfully logged in using the Private Access button but it didn't ask me for the two factors authentification code.
I was then unable to see my private repo.

Here is a GIF explaining the problem better than me.

That's pretty weird. Could you try logging out, revoking access from DevSpace on GitHub (https://github.com/settings/applications), and then logging again with private access?
