Two-Factor Authentication
Two-Factor Authentication (2FA) is a security method that requires users to provide two different types of verification to prove their identity before gaining access to an account or system. It adds an extra layer of protection beyond just a password.
TECHNICAL DEFINITION
Two-Factor Authentication (2FA) is a robust identity verification mechanism requiring two distinct authentication factors—something you know (e.g., password), something you have (e.g., security token, phone), or something you are (e.g., biometric)—to enhance access control security and mitigate unauthorized access risks.
BACKGROUND
Computer security is a subdiscipline within the field of information security. It focuses on protecting computer software, systems, and networks from threats that can lead to unauthorized information disclosure, theft, or damage to hardware, software, or data, as well as to the disruption or misdirection of the services they provide.
