Use case

The scam-proof family safe word.

Voice-cloning scams call your parents with your voice and beg for money. The defence is old-fashioned: a safe word only your family knows. The mistake is storing it in a group chat. Seal it instead.

What is a family safe word and where should you keep it?

A family safe word is a pre-agreed secret word or question used to verify identity when a call or voice message asks for money or help — the standard defence against AI voice-cloning scams. Keep it out of chat apps and email; store it in an encrypted vault the whole family can open, like a shared Sealby vault.

Beats a cloned voice

A scammer can copy a voice from a social clip, but not a secret that never appeared online. “What’s the word?” ends the call.

Shared with family, not with servers

With Premium vault sharing, everyone keeps the safe word — plus the “what to do if someone calls” checklist — in a vault no service can read.

The whole protocol, not just a word

Store the backup question, the callback rule, and emergency contacts as a sealed note. In a panic, nobody has to remember — just unlock.

Common questions

Why not just put the safe word in our family group chat?

Chat apps sync to servers, old devices, and backups you don’t control — and a compromised account hands the scammer your defence. An encrypted vault keeps the word readable only to family members who hold the key.

What makes a good family safe word?

Something memorable but never posted anywhere: an inside joke, a childhood detail, an invented phrase. Add a backup question in case someone blanks, and agree that money requests without the word always get a callback on a known number.

How do voice-cloning scams actually work?

Scammers lift 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 — and pressure them to send money before checking. A safe word breaks the script instantly.

Your vault is waiting.
