 Banks say voice authentication is an extra layer of protection against fraud and cyber crime. But is it really worth it? If you're skeptical of your bank having your voice data on record, you're not crazy. You're smart. A voice can be cloned using AI for just a few dollars with as little as 10 seconds of audio. Frightening. No matter how much money you have in the bank, hackers want it. Call your bank's customer service line that you see on its official website and opt out of voice authentication. And if a bank is asking for your voice, say no.
