@scottalanmiller I think your confusing Two Factor Authentication with SMS.
No, I definitely know what both are. I think you are quoting someone who was wrong in the article because someone said that to them there too trying to claim that a code over SMS isn't two factor authentication, but it most certainly is as they get pointed out in the article too.
All the images I see of Authy show it uses SMS codes as its second factor. Hence why I thought that that was what they used. If they don't use insecure SMS, why do they advertise it so much?

Also, you can use Authy completely offline

I see on their site that SMS is a fallback. They show way too many pictures of it, it make it look like SMS was the process, not an emergency fallback for people living in the dark ages.
