Learn More About Multi-Factor Authentication

Person using multi-factor authentication

Multi-factor authentication is a security feature offered by many websites, applications and devices that dramatically improves account security. It’s also sometimes referred to as two-step verification or dual-factor authentication, is a security process in which end users provide two different authentication factors to verify themselves.

If you have multi-factor authentication set up for a given account (website, application or device), when you log in with your username and password, that account server is going to ask for a second, independent form of authentication before it will actually let you into the system. It’s kind of like when you open a bank account and they ask to see a picture ID and some other form of identification, like your social security card or a passport. It’s much harder to pretend you are someone you’re not when you have to prove who you are in two different ways.

There are several methods for which multi-factor authentication can be achieved, including:

  • Push
  • Mobile Device Code
  • SMS Code
  • Email Code
  • Physical Token
