Two-Factor Authentication

Two-Factor Authentication (2FA) is a type of multi-factor authentication that serves as an added layer of security designed to ensure that only certain verified personnel have access to accounts and information. It does this by confirming the users’ identity using the combination of two factors instead of gaining access immediately. For example, if a person enters their username and password they are then prompted to provide another piece of information regarding something they either know, have, or are.

  • Something you know: May include an additional password, personal identification number (PIN), a keystroke pattern, or answers to “secret” questions
  • Something you have: May include a badge, additional key, credit card, or smartphone
  • Something you are: May include a scan of your iris, fingerprint, or voice recording

Two-Factor Authentication can drastically reduce the risk of data breaches, identity theft, and other online fraud. This extra layer of security makes it much more complicated for cybercriminals to get through. Security has grown as a worldwide issue, and we believe that 2FA is a must-have for all applications.
