SCP Exam SC0-502 Topic 2 Question 9 Discussion

For the past month, the employees in the executive building have been getting adjusted to their new authentication systems. There was a large spike in help desk calls the first week, which has gone down daily, and now there are fewer login related calls than there was when the office used passwords alone. During your weekly meeting with Blue, the authentication subject is discussed, "So far, the system is working well. Our call volume has dropped, and it seems that most people are getting used to the tokens. There is one issue, however." "Really, what's that?" you ask. "It seems that the senior executives are not that keen on carrying the new tokens around with them. They are asking for a way to authenticate without carrying anything, but still have it be secure." "All right, do we have a budget?" "Yes, however there are not that many senior executives, so the cost isn the primary issue; although we do want to keep the costs down as much as possible." "So, what limitations do I have?" "Well you need to be sure it easy to use, is unintrusive, won't require too much training, won't be all that expensive, and provides for strong authentication." Blue tells you. Based on this information, choose the best solution to the authentication problem for the senior executives on the fourth floor.}
