This is a tremendously extraordinary statement in need of a huge proof.

terms "extra layer" and "better" point to merely a cloud of human feelings.

I can accept the premise for this statement:
adding SMS to password reduces false-positive auth outcomes.
(no matter how much and how needed)

But it also increase false-negative auth outcomes!!!
AND THIS REALLY HURTS.
and I speculate sometimes it hurts the security too.


and after all, as you now witnessing, when a logically inconsistent 
bullshit becomes accepted as a part of an info system, it tends to 
overthrow the logic of the host system and turn it into crap entirely.
Same goes to the password policies.
