OpenAI CEO Sam Altman delivered a sobering message to America’s financial industry this week, warning that Artificial Intelligence has rendered traditional voiceprint authentication all but obsolete—and that banks urgently need to rethink how they protect customers from fraud.

Speaking at a Federal Reserve conference in Washington, D.C., Altman warned top executives and regulators that powerful AI voice-cloning tools now allow cybercriminals to mimic anyone’s voice with just a few seconds of audio. This, he said, marks the beginning of a massive fraud crisis, as institutions are left exposed to criminals able to bypass outdated security checks with alarming ease.

“A thing that terrifies me is apparently there are still some financial institutions that will accept the voiceprint as authentication. That is a crazy thing to still be doing. AI has fully defeated that,” Altman told the audience.


A New Cybercrime Era

Altman’s comments reflect the explosive growth and accessibility of AI-powered deepfake tools. Technology that once required complicated setups and expertise is now readily available—and powerful enough to fool both people and automated phone systems. Consumer Reports found that journalists were able to use AI voice clones to access real bank accounts at major U.S. institutions, exposing just how serious the vulnerability has become.

According to industry analysts, AI-related scams resulted in $12 billion in losses in 2023, with that number expected to surge past $40 billion annually by 2027. All it takes is a few seconds of someone’s speech—often easily scraped from social media or phone calls—for AI to mimic voices convincingly.


Regulators Ready to Respond

The Federal Reserve’s vice chair for supervision, Michelle Bowman, moderated Altman’s panel and expressed interest in working with technology leaders on new security standards. “That might be something we can think about partnering on,” Bowman said, signaling an unprecedented opportunity for government and tech sector collaboration.

Data shows that over 90% of U.S. banks are already reconsidering voice-based verification due to the growing threat. Experts suggest biometric and multi-factor authentication, as well as behavioral analytics and AI-driven fraud detection tools, will become essential in the near future.


Practical Protection for Consumers

Altman advises everyone to stay wary of voice and video calls involving unusual requests or sensitive information—even if the caller sounds like a friend, family member, or authority figure. As deepfakes become more advanced, consumers should expect to see stronger verification methods and learn how to spot the warning signs of scams.


A Pivotal Moment for AI and Security

Altman’s visit to Washington coincides with broader government action on AI, as the White House prepares to launch an “AI Action Plan.” While OpenAI and others tout AI’s potential for economic and societal good, they also recognize that proactive security and regulation are urgently needed to protect consumers from sophisticated new threats.

The message from Altman is clear: AI fraud is not a distant threat, but a present crisis requiring rapid, coordinated action from banks, regulators, and the public alike.
