Multi-Factor Access Control Authentication Guide

By: Brian Rhodes, Published on Dec 10, 2018

Can a stranger use your credentials? One of the oldest problems facing access control is making credentials as easy to use as keys, but restricting them to certain individuals.

Multi-factor authentication is used when the end-user is concerned about who can use access control credentials. 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
  • What Drawbacks Multi-Factor Authentication Have
  • Why Single Factor Authentication Is Still Common
