Question

Quizplus · Accepted Answer

Two-factor authentication (2FA) is a security process that requires the user to provide two different authentication factors to verify their identity. The factors are typically something the user knows (password or PIN) and something the user has (security token or code sent to a registered mobile device). This adds an extra layer of security to prevent unauthorized access to sensitive information.
