MFA stands for Multi-Factor Authentication. The purpose of multi-factor authentication is to have multiple security layers before someone can login to an application.

The goal of MFA is to make is so only you can be the one to access your desired account. Using a second layer of security like a security question that only you would know, a texted code that only you would receive, or a biometric element only you could provide is the easiest way to ensure YOU are the only one that could login to your account.

Types of MFA:

  • Password
  • Security Question
  • Emailed, Texted, or Automated call with a 4-6+ digit code
  • Authenticator App (random code generator)
  • Biometric Authentication (fingerprint, face, iris, voice, etc.)
  • Confirmation Email

Most commonly, only 2 forms of MFA are used to help ensure security. This is known as 2-factor authentication or 2FA. When it comes to logging into apps, the most widely used set of MFA is entering your password followed by a texted 6+ digit code. However, to enter more important sites like your banking institute or medical records, a password plus a biometric layer like a fingerprint or facial recognition is suggested or even required.
