An authentication factor is a piece of information and process used to authenticate or verify the identity of a person or other entity requesting access under security constraints. Two-factor authentication (T-FA) is a system wherein two different factors are used in conjunction to authenticate. Using two factors as opposed to one factor generally delivers a higher level of authentication assurance.

dbpprop:abstract
  • An authentication factor is a piece of information and process used to authenticate or verify the identity of a person or other entity requesting access under security constraints. Two-factor authentication (T-FA) is a system wherein two different factors are used in conjunction to authenticate. Using two factors as opposed to one factor generally delivers a higher level of authentication assurance. Using more than one factor is sometimes called "strong authentication", however, "strong authentication" and "multi-factor authentication" are fundamentally different processes. Soliciting multiple answers to challenge questions may be considered strong authentication but, unless the process also retrieves 'something you have' or 'something you are', it would not be considered multi-factor. The FFIEC issued supplemental guidance on this subject in August 2006, in which they clarified, "By definition true multifactor authentication requires the use of solutions from two or more of the three categories of factors. Using multiple solutions from the same category ... would not constitute multifactor authentication.
