Two Factor Authentication (TFA or 2FA) is also called strong authentication and is a security process which requires two independent mechanisms for authentication. Â 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. Â Two factor authentication is used generally in electronic computer authentication where stronger means of authentication is needed to protect sensitive data. Â 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. Â Two factor authentication can be used in these instances to decrease the probability of a non authorized user to access this information.
