Definition - What does Two-factor Authentication (2FA) mean?

Two-factor authentication, or 2FA, is a feature that works as a dual layer of protection against fraud that restricts access to the owner of an account via username/password login, plus a 2FA mode toggled by its user. A 2FA protocol is an approach to help mediate data breaches among points of contact. Text messages, mobile apps, and biometrics are front-end methods to buffer security threats.

SureHire explains Two-factor Authentication (2FA)

Statistics mark a rise in cybersecurity threats giving way to 2FA endpoints where a user holds exclusive access via a service module to avoid the risk of a data breach. Many field experts support 2FA methods to help close the gap between Intranet terminals and external hosts where data theft is an issue. 2FA methods often use open-ended routers where it is easy to tether personal and corporate devices across in-house systems.


However, many data breaches stem from mislaying devices and sharing electronic data (i.e., passwords) with colleagues in the workplace. A spillover of eCommerce fraud can expose sensitive data where financial and health information is at risk. A company 2FA or multi-factor authentication (MFA) policy, like that used by SureHire for our staff and clients, can help offset leakage from the mix.
