"Everybody hates multi-factor authentication," cybersecurity expert and former government hacker Kyle Hanslovan tells CNBC Make It. Microsoft has claimed that multi-factor authentication can prevent 99.9% of cyberattacks on personal accounts. Fewer than half of U.S. small business-owners require employees and customers to use multi-factor authentication, according to the Cyber Readiness Institute. They're more likely to choose the path of least resistance whenever they come across an obstacle, like an extra step for authentication, Hanslovan says. "If you [use multi-factor authentication] and choose that app, you're almost ahead of most of the pack and attackers will move to somebody who's the slowest one."
