Two Factor Authentication (TFA or 2FA) is also called strong authentication and is a security process which requires two independent mechanisms for authentication. Two factor authentication implies the use of two out of the three factors to assert an entity’s identity to another entity. The three factors are: Something you know, like a Personal Identification Number (PIN); Something you have, like a mobile device for receiving a one time password or ATM card; Something you are, like a face scan, iris scan or your fingerprint. Two factor authentication is used generally in electronic computer authentication where stronger means of authentication is needed to protect sensitive data. For example, electronic personal health information (ePHI) on a computer accessed by many different individuals can be exposed and can result in HIPAA fines and violations for the medical institution. Two factor authentication can be used in these instances to decrease the probability of a non authorized user to access this information.
