 By having an audio snippet of your nephew's voice, it could be easy to make them say whatever it is that they want to say. So that's why it's important to be able to vet that person, whether it's by using a code word or asking them a bunch of questions that only that individual would actually know in order to verify and make sure that they're real. It's never easy. Thanks, Cordelia. Cordelia James, personal tech reporter at The Wall Street Journal. We're coming up on 30 minutes after the hour now.
