A method for checking that a user (person) is the one claimed.


Verification that an entity is the one claimed is generally done through the usage of authentication factors. An authentication factor is a piece of information and process used to authenticate or verify a person’s identity for security purposes. Two-factor authentication is a system wherein two different methods are used to authenticate. Using two factors as opposed to one delivers a higher level of authentication assurance.

There are three universally recognized factors or a combination thereof for authenticating individuals:
  1. Something the person knows

  2. Something the person possesses

  3. Something the person is (using a personal characteristic)

Using something only the person knows is the “classical way” to corroborate a user’s identity based on a secret piece of information such as a password, a PIN code, a pass-phrase, etc.
