A company’s security policy requires all employees to use a secure method for accessing corporate email on their mobile devices. The IT department has implemented a solution that requires not only a password but also a verification code received on another device owned by the user. During setup on an employee’s smartphone, which of the following best describes the additional security measure being implemented?
Two-factor authentication adds an extra layer of security by requiring two different types of identification before access is granted. In this case, the policy specifies that a password (something the user knows) and a verification code sent to another device (something the user has) are required to access corporate email, fitting the definition of two-factor authentication.
