# Family Safe Word: How to Set One Up Against AI Scams

> A family safe word is a word or phrase agreed in person that any relative must give before you act on an urgent call for money or help. Pick something that appears nowhere online, share it face to face, ask for it without hinting at the answer, and change it after it has been used once.

The FBI does not often give advice that costs nothing and takes five minutes. Its December 2024 warning about AI-assisted fraud does exactly that: "Create a secret word or phrase with your family to verify their identity" ([FBI IC3](https://www.ic3.gov/PSA/2024/PSA241203)). Starling Bank in the UK has run a whole campaign around the same idea, after a survey it commissioned found that 28 percent of adults believed they had been targeted by a voice cloning scam in the previous year.

The idea is old. Parents have given children code words for school pick-ups for decades. What is new is that a stranger can now sound exactly like your daughter. Your safe word moves the test from "does this sound like her?" to "does this person know something only she knows?". Software can fake the first. It cannot fake the second.

## Why a safe word works when your ears don't

Cloned voices can be convincing, and people are bad at telling the difference. For a 2023 UCL study, listeners had to spot synthetic clips and identified synthetic speech only 73 percent of the time, even though they knew fakes were in the mix. Our guide to the [AI voice cloning scam](https://fake-ai.com/voice-and-scams/ai-voice-cloning-scam/) explains how little audio a scammer needs.

Sharing a secret sidesteps the whole question of audio quality. It also gives the person receiving the call something concrete to do in a moment of panic. "Ask for the word" is easier to remember at 11 pm than "listen for metallic artefacts".

## How to choose a word nobody can research

Scammers prepare. They scroll through public profiles to learn names, schools, holiday plans and pets. Anything that has ever been posted is a bad choice.

**Safe word candidates: good and bad**

| | Findable online? | Easy to remember? | Verdict |
|---|---|---|---|
| Name of the family dog | yes | yes | Avoid |
| Grandma's birthday | yes | yes | Avoid |
| Street you grew up on | partly | yes | Avoid |
| Two unrelated words: **teapot glacier** | no | yes | Good |
| Nonsense word from a family joke | no | yes | Good |
| Random 12-character password | no | no | Too hard under stress |

Two random words work well. Pick them by opening a book on a random page, or let each family member contribute one word. The result should sound odd enough that nobody would say it by accident, and memorable enough for an 80-year-old to recall when frightened.

## Set it up in four steps

**Setting up a family safe word**

1. **Agree in person** At a family meal or on a video call you started yourself. Never by text, email or social media.
2. **Decide who is in** Usually parents, grandparents, teenagers and anyone who handles money for an older relative.
3. **Agree the rule** No money, passwords or bank details to anyone who calls in an emergency without the word, whatever they sound like.
4. **Practise once** Do a test call so everyone knows how it feels to ask. It is awkward the first time and easy after that.

Write it down only where a thief wouldn't look and where it won't sync to the cloud. Notes apps that back up to an email account are not a good hiding place. For older relatives, a card in a wallet is reasonable, as long as it doesn't say what the word is for.

## How to ask without giving the word away

This is where most families get it wrong. If you ask "Is the word teapot glacier?", you have just told the scammer the word. Ask open questions instead.

Phrases that work:

- "Before we go on, what's our word?"
- "I need the family word first. What is it?"
- "Grandma said to ask you for the word. Go ahead."

If the caller dodges, claims they're too upset, says the line is bad or asks you to say it first, treat that as the answer. Hang up and call the person back on the number you have saved. That second step catches the cases where a real relative has forgotten the word in panic.

Some families add a duress signal: a second word that means "I'm saying what someone is making me say". That is optional and only worth it if everyone can keep two words apart.

## Talking to older relatives about it

Grandparents are the classic target of the emergency call. The American name for it, the grandparent scam, says as much. They are also the group most likely to find the idea of a code word silly or insulting. How you frame it matters.

Don't present it as "you might fall for a scam". Present it as something the whole family does, including you, because criminals can now copy anyone's voice, yours included. Show them a news report about a cloned-voice call. Then make the rule mutual: you will also ask them for the word if a call from them sounds strange.

Make it concrete, and keep it short. One rule, one word, one practice call. Older relatives sometimes worry they will be rude to a real grandchild in trouble. Tell them explicitly that you would rather be asked for the word ten times than lose their savings once, and that hanging up and calling back is always allowed. Permission to be "rude" is what many of them need.

## Rules for after it's been used

Change the word once it has been spoken on a phone call, even if the call was genuine. You don't know who was listening on the other end or whether the line was recorded. Also change it if someone writes it in a message, or if a family member falls out with the group.

Review it once a year at a family gathering. That is also a good moment to repeat the rule: no word, no money, no exceptions.

## Where a safe word doesn't help

Safe words protect calls that claim to come from someone in your inner circle. It does nothing against a fake bank adviser, a fake police officer or a fake tech support call, because those callers don't pretend to be family. For those, the rule is to hang up and call the organisation on the number printed on your card or its official website.

It also doesn't cover messages. Text and messenger scams that start "Hi Mum, I've got a new number" are better handled by calling the old number. If the old number works and your child answers, you have your answer.

At work, the equivalent of a safe word is a payment verification procedure. We cover that in [deepfake CEO fraud](https://fake-ai.com/voice-and-scams/deepfake-ceo-fraud/). Teams that want such checks built into their internal tools can ask a developer such as [OnlineBuilders](https://onlinebuilders.biz/solutions/ai-bots). At home, the next step is shorter: pick two words tonight and tell your family in person.

## FAQ

### What is a good family safe word?

Something random that no one could research, such as two unrelated words or a nonsense phrase from a family joke. Avoid pet names, birthdays, street names and anything that has appeared in a social media post.

### Should children have a safe word too?

Yes. The same word can protect children from strangers who claim a parent sent them, a use that predates AI by decades. Keep it simple enough for them to remember under stress.

### What if my relative forgets the word during a real emergency?

Then fall back to the call-back: hang up and call them, or someone with them, on a number you already have. A forgotten word is a reason to verify another way, not a reason to send money.

### Is a safe word enough on its own?

No. It works best combined with the habit of calling back on a known number. Starling Bank, which runs a safe phrase campaign in the UK, notes that safe words can be compromised, for example if someone shares it in a message that is later hacked.
