That covers entering a PIN/Password on your phone. I have yet to use any google/apple product requiring me to use this. Only ones ive seen from google or apple is receiving a text/email with a code that you type into your browser. SFOR patent does not cover that.
Now do I thnk SFOR patent is superior to a text code? Yes it is simply for the fact that if your phone is ever stolen you are still protected.
I still have yet to see any product using their patent besides Microsoft Azure.
