Paper 10-1:  Two factor authentications add more security to any application.  This is well documented in the security realm.  The problem tends to be how the 2FA is offered.  Having to input a long string of randomly generated characters from a keyfob is irritating.  Having to enter a second password or some other kind of information can be frustrating to end-users as well.  This paper discusses a technology called Sound-Proof, which uses audio based on proximity to a device as a 2FA method.  After reading the article, post an analysis in 600 words or less.
