Beats a cloned voice
A scammer can copy a voice from a social media clip, but not a secret that never appeared online. “What’s the word?” ends the call.
Use case
Voice-cloning scams call your parents with your voice and beg for money. The defense is old-fashioned: a safe word only your family knows. The mistake is storing it in a group chat. Seal it instead.
A family safe word is a secret word or question agreed in advance. You use it to check who is really calling when a call or voice message asks for money or help. It is the standard defense against AI voice-cloning scams. Keep it out of chat apps and email. Store it in an encrypted vault and share a sealed copy with your family, like a shared Sealby vault.
A scammer can copy a voice from a social media clip, but not a secret that never appeared online. “What’s the word?” ends the call.
With Premium vault sharing, everyone in the family keeps the safe word, plus the “what to do if someone calls” checklist, in a vault no service can read.
Store the backup question, the callback rule and emergency contacts as a sealed note. In a panic, nobody has to remember anything. Just unlock.
Chat apps sync to servers, old devices and backups you don’t control. A hacked account hands the scammer your defense. An encrypted vault keeps the word readable only to family members who hold the key.
Something memorable that was never posted anywhere: an inside joke, a childhood detail, an invented phrase. Add a backup question in case someone blanks. And agree that any request for money without the word always gets a callback on a known number.
Scammers take a few seconds of voice from social media or voicemail, clone it with AI, then call a relative with an urgent story: an accident, an arrest, a kidnapping. The relative is pressured to send money before checking. A safe word breaks the script instantly.
