What is Two-factor authentication?
Def#1 Two-factor authentication is based on something a user knows (factor one) plus something the user has (factor two). In order to be authenticated during the challenge/response process, users must have this specific (private) information. Def#2 Two-factor authentication provides a higher level of trust than passwords alone because it requires something a user knows, such as a password, as well as something that person has, such as a smart card or a token. Def#3 This is a process controlling the authenticity of the users identity on the basis of the two following factors: Something You Know — for example, the user name and password. Something You Have – for example, the CD device. Def#4 Two-factor authentication (T-FA) is an authentication protocol that requires two forms of authentication to access a system. This contrasts with traditional password authentication, which requires that a user only know a password to gain access to a system. ------------- MBA Examination papers
