Cybersecurity Month: Multi-Factor Authentication (MFA)

Week 1

Today’s topic is Multi-Factor Authentication (MFA), also known as 2 Step Verification (2SV). Harvard’s MFA solution is DUO.

What is MFA?

MFA is a process to identify a person multiple ways. It insures a stolen password itself doesn’t lead to a stolen email, banking, or social media account.

The 3 Factors of MFA

1. something you know: password or phrase PIN, 2. something you have: code from app or SMS push notification USB token, 3. something you are: finger or thumb print, face scan, iris scan

  1. Something you know (Password, phrase or PIN)
  2. Something you have (Code from an app, SMS, Push notifications USB token)
