Final answer:
Lauren will have implemented three distinct factors when she is done. Lauren's multi-factor authentication system will include three distinct factors: a passphrase, a time-based code generator, and a PIN, each representing a different type of authentication factor. Therefore, the correct answer is C. Three.
Step-by-step explanation:
Lauren will have implemented three distinct factors when she is done. The passphrase, time-based code generator, and PIN are all separate factors that contribute to the multi-factor authentication system. Each factor adds an additional layer of security to the authentication process, making it more difficult for unauthorized individuals to access sensitive information.
Lauren's multi-factor authentication system will include three distinct factors: a passphrase, a time-based code generator, and a PIN, each representing a different type of authentication factor.
Lauren is designing a multi-factor authentication system, incorporating a passphrase, a time-based code generator, and a PIN. Each of these components represents a different factor in the authentication process. A passphrase is something the user knows, the time-based code generator is something the user has (because it's typically linked to a device that generates the codes), and the PIN is an additional knowledge factor. Therefore, Lauren has implemented three distinct factors for the authentication system.
Lauren's multi-factor authentication system incorporates three distinct factors: a passphrase, a time-based code generator, and a PIN. Each of these factors represents a unique authentication element that adds layers of security to the system.
The first factor, a passphrase, involves something the user knows, typically a memorized secret like a password or phrase. This is a common and fundamental factor in authentication systems.
The second factor is a time-based code generator, which falls under the category of something the user possesses. These devices generate temporary codes that change at fixed intervals, adding an additional layer of security by requiring a dynamic and time-sensitive element for authentication.
The third factor, a PIN (Personal Identification Number), is also something the user knows. It is a numeric code that the user enters to further validate their identity. Combining the passphrase and the PIN ensures that two knowledge-based factors are employed, enhancing the overall security posture.
In total, Lauren's multi-factor authentication system encompasses three distinct factors – something the user knows (passphrase and PIN) and something the user possesses (time-based code generator). Therefore, the correct answer is C. Three. This multi-factor approach significantly strengthens the security of the authentication process by requiring multiple forms of validation, reducing the likelihood of unauthorized access.
