In the "also my goldfish has an IPhone" era, in my opinion I think it is almost impossible to secure yourself temporarily to the fullest. I tell you why:
A hacker isn't just someone who tries to steal your password and that's it. A hacker wants a challenge, which he finds in every new-created security software/program for mobile devices or etc.
Somehow we have to stay also analog. Just look at the Swombies (Smartphone Zombies - yes, that is a word), who sit in the tram not looking at each other, ignoring themselves and laughing at some stupid clips or something. Wake up people, it's getting worse.
Great experiment, though !! Like this thought)) thank you!
