Git password prompt: clarify what value to enter if GitHub 2FA is enabled

[ronaldtse]

If GitHub two factor authentication is enabled, the password prompt will keep being prompted without explaining why.

The workaround is to go to GitHub Settings > Personal Access Token and generate one with “repo” functionality to be able to make the pushes.

If the editor app detects that two factor is enabled, it should prompt the user to create a password access token.

To work around the password requirement, the options are:

• Request to create a personal token like suggested in the description
• Allow to specify SSH key, if Git is installed locally it may be possible to make work, but not certain
• Support OAuth (this is the least certain way from previous experience)

I’m going to go with the personal access token for now.

By the way, the app may not be able to tell if authentication error is due to 2FA or wrong password. This will be made part of the docs, to which password prompt should link.

I’m not a fan of tying our app to GitHub, it’s meant to support any Git implementation. Additionally, 2FA means potentially supporting integrations with multiple Git hosting provider APIs in future, which may be overhead we’re unable to bear yet.

No objection to documenting GitHub-specific issues like this one, though.
