One of the most significant capabilities in the enterprise defensive arsenal is multi-factor authentication. There is no such thing as a single silver bullet that will mitigate all risks, but in today’s world if you do not have multi factor authentication in place you are almost negligent in your defense.

This point is best shown vice described. See the video at this link and embedded below:
The point of the video is not just to see weakness, but to learn best practices. Please share this with the members of your team working on your two factor authentication programs, they will appreciate knowing this.
