What is required to enable 2FA for a user?

To enable two-factor authentication (2FA) for a user in NetSuite, it is essential to have a mobile device that can receive the verification code. This mobile device typically runs an authentication application that generates time-sensitive codes or can receive SMS messages containing verification codes. The purpose of 2FA is to add an additional layer of security beyond just a username and password, and having a mobile device that can handle these codes is crucial for that process.

While other options mention elements that might seem related to user security, none fulfill the requirements for 2FA as effectively as having a mobile device. A secure password alone is not sufficient for 2FA, as it only represents the first layer of authentication. Similarly, while an email address can be used for verification purposes in some contexts, it is not a requirement or part of the standard process for enabling 2FA in NetSuite. Lastly, simply downloading a mobile app does not complete the 2FA setup; the user must also utilize the app or device to generate or receive the verification codes. Thus, possessing a mobile device to receive the verification code is a necessary requirement for enabling 2FA.
