Two-factor Authentication
Two-factor authentication (2FA) is a security process that requires users to provide two different authentication factors to verify their identity. These factors can be something the user knows (such as a password or PIN), something the user has (such as a smart card or mobile device), or something the user is (such as biometric data like fingerprints or facial recognition). By requiring two different factors, 2FA provides an extra layer of security that makes it more difficult for unauthorized users to access sensitive information or systems. In the context of data science and artificial intelligence, 2FA can be used to protect sensitive data or models from unauthorized access or modification.
