2FA and the /r/science incident

Having 2 factor authentication would have prevented this and saved the reddit admins from the work of reverting these changes.

I do believe that requiring all mods of certain sized subreddits to enable 2FA should be a thing, or, at the very least, letting subreddits have control over the requirement in the subreddit settings.

I remember reading about the site admins having this functionality. Is there a timeline for this for moderators at all?
