WHILE REWINDING the sound track of my life, I remembered my first use of Two-Factor Authentication (2FA) while working in the largest office building in America. Back then, I wouldn't have considered blogging about it.
We used 2FA with cypher keys and it validated the identity or credentials of someone who wanted to put eyes on subject material. Today, 2FA is a process using two methods, such as a password and a physical card. Back in the early 80s, we had to punch in numbers in a keypad and then consult a written card for the date to correctly enter a key sequence behind a second door.
Behind those same doors today, the second factor now uses RFID along with biometric technology (such as fingerprint, face or iris recognition). Beyond the military, 2FA features in special information networks,financial or banking transactions. I use the simplest 2FA with my Chip and PIN card.
I'm watching 2FA gain increased sophistication through the use of physical objects such as NFC, USB, and biometric technology. I expect to see it integrated into our cars before the end of the decade.
