By Brian Rhodes, Published Nov 15, 2021, 10:15am EST

Unauthorized users gaining access with someone else's credentials is one of the most fundamental risks of access. Multi-factor aims to mitigate that.

Multi-factor authentication means that more than one credential must be presented in order to gain access. However, the credentials are 'layered' in a way that they complement each other and reduce the probability of unauthorized individuals gaining access.

In this guide, we explain the concept and the elements involved, including:

  • What Does Multi-Factor Authentication Mean?
  • What Benefits Multi-Factor Offers
  • The Four Factor Types Available
  • Which Factors Are Common For Access Control
  • Why The Biometric Factor On Mobile Is Not A True Multi-Factor Method
  • What Drawbacks Multi-Factor Authentication Have
  • Why COVID has Negatively Impacted Fingerprint Factors
  • Why Single Factor Authentication Is Still Common
