Google Authenticator can be completely disconnected from google’s API though. And hell no on that FB API. The whole reason I am using MIAB is to guard against similar shit that they do. lol I am not saying I am a “super coder”, and I would do the pull request, however, I am currently working on too many projects of my own (https://urgero.org) see my site if you would like.
That being said, It wouldn’t be the first time I have done an “add-on” for MIAB I also wrote a quick and dirty external registrator and authentication tool for PHP, as well as a mod to allow MIAB to become a hyper-visor.
I am sorry if I offended, that was not my intention, was just trying to point out a solution that should be simple for someone to implement.
