Google Two-Factor Authentication Module for Shield

As the title explains I've created a module for use with Shield that provides two-factor authentication using the Google Authenticator app. I explain in more detail on a thread regarding Docker. Instead of using email or SMS, this uses an on-screen QR code to generate Time-Based One-Time Passwords. It is a fork whose repository structure and code have been modified to act as a pluggable module. It has two Composer prerequisites: Google2FA, and BaconQRCode.

I called it Halberd, and I hope it helps.
