I had posted this but someone had moved it to Firefox and Android. But there is still no answer on my question?

How do I scan the authy barcode through the authy app on my android phone in order to login to firefox? other wise firefox will not allow me to login without useing the authy or google authenticator? Also how do I scan the barcode through Google authenticator? Thank's. And i don't have a screenshot of it? The problem is on my phone not on the desktop. And I think that my question is pretty much self eplanatory when someone read's it. Thank's.
