Not just to secure your GMail account, but also extremely helpful to tighten the security of your SSH connection as instructed at http://www.mnxsolutions.com/security/two-factor-ssh-with-google-authenticator.html

No documentation. No syncing, so can't import my existing 2FAs. Appears to only be useful if setting up a new 2FA - given I've already put all my 'at risk' accounts onto 2FA, makes this useless.
