Using ambient sound as a two-factor authentication system

A posting from naked security titled  ” Using ambient sound as a two-factor authentication system” by Lee Munson

We know that many of us are no good at choosing our own passwords. That’s why companies are increasingly looking to bolster their own website security through additional authentication methods.

To that end, we’ve seen many different forms of two-factor authentication (2FA) employed – John Shier wrote an excellently detailed article on the topic last year in which he noted that each of the common 2FA optionshave their disadvantages.
