Re: '2 Factor- This is proper security'
Lets face it the biggest problem with the text-based 2FA is not someone hacking the phone company's network but that likelihood that a user is relying on their phone for both the web login AND the text message.
So that dual-use phone becomes a single point of security failure, more so given the piss-poor patching and updates for most Android phones (i.e. most phones in total).
So use text-based 2FA if you possibly can, but please don't do both one the one device!
