Two factor authentication(T-FA) or (2FA):a security process in which the user provides two means of identification in conjunction, one of which is typically a physical token, such as a card, and the other of which is typically something memorized, such as a security code. Using two factors as opposed to one factor generally delivers a higher level of authentication assurance. Two-factor authentication typically is a signing-on process where a person proves his or her identity with two of three methods: "something you know" (such as a password or PIN), "something you have" (ex.: smartcard or token), or "something you are" (ex.: fingerprint or voiceprint analysis).(1)
