AI can clone a loved one's voice in 3 seconds. FamWord gives your family rotating secret words a clone can never know. The FBI recommends a family code word — but a static word can be overheard. FamWord's words change every 30 seconds: nothing to steal, nothing to memorize. Set up with a QR code, no accounts. On a suspicious call, ask for the three words. Match — it's them. No match — hang up. Works offline, no tracking. One purchase covers the whole family. Free for 7 days.
