Protect your family from Deepfake AI Impersonations
One daily word.
Every family phone.
One shared defense.
Deepfake voice and video impersonation scams are becoming more common. Scammers can impersonate the people you love and create a false emergency in seconds.
Before you believe what you hear or see, ask:
“What is today’s Family Moat code word?”
Family Moat delivers a new secret code word to every family member’s phone each day.
The voice may be fake.
The video may be fake.
The code word isn’t.
Family Moat.
Your family’s defense against deepfake impersonation scams.
Trust proof
The FBI, the FTC, and major banks are already urging clients to use a secret family code word.
But a code word only works if everyone knows it, remembers it, and updates it. That’s where most families fail.
Family Moat automatically delivers the same fresh code word to every authorized family phone, every day.
No forgotten passwords.
No outdated code words.
No scrambling during a crisis.
Just one simple question that can expose an AI impersonator.
Banks and regulators recommend family code words. They do not endorse Family Moat. Family Moat makes the recommendation work.

Read what they say
You need a family code word.
The problem
AI generated deepfake voice and real-time video scams turn love and panic into payment pressure.
When a call sounds exactly like someone you love, panic takes over. A unique daily code word cuts through the fear and turns uncertainty into one simple question.
What these calls sound like
Having a unique daily code word your family can always ask — no matter how convincing the voice or video — turns panic into a simple question.
Why Family Moat
AI can copy the voice and image of you and your loved ones — it cannot copy the daily family code word.
Provides a unique daily family code word
Ask for the code word to confirm it’s really your loved one on any call or video chat.
Works without internet
A unique code word is generated on your device. It works during outages or travel.
Stores nothing online
No server-stored code words to leak or steal.
Uses proven cryptography
Powered by HMAC-SHA256, a battle-tested cryptographic standard relied upon across banking, government, and critical infrastructure.
Same scam, two endings
The same fake emergency has two very different endings.
The call is received. The money is lost.
Without a verification tool, decisions are driven by emotion alone, and money moves in seconds.
Three seconds of public audio is enough to produce a convincing clone of a specific person.
Parent hears their child in apparent distress. Recognition happens in under a second.
“Hang up and call back” fails under emotional pressure with a real-sounding loved one on the line.
The bank’s anti-fraud stack sees a customer-initiated, fully-authenticated payment. Nothing to flag.
One question stops the scam attempt immediately.
With a daily shared word on every family member’s phone, a cloned voice can sound believable, but it cannot produce the correct code word.
Nothing changes on the attacker’s side. The clone is just as convincing.
Daily habit. The shared family word is already on the screen, generated on-device.
“What’s today’s word?” The real son knows it. The clone does not — and cannot guess.
Parent hangs up and calls the real family member on a known number to confirm safety.
The solution
One daily code word. Every family phone. Ready when it matters.
Family Moat gives your family a simple verification habit before anyone sends money, shares private information, or acts under pressure.
Download the Family Moat app
One member of the family creates an account as administrator of the “Family Moat”.
Invite your family members
Family members who have also downloaded the app will receive a notification to join. Only the administrator is charged.
Start receiving your code words
Family Moat shares a daily changing code word with members of the Moat.
Stay protected
Refer to Family Moat any time you need to confirm a family member’s identity.
One code word. Every day. Every family member’s phone.
Watch the day’s code word count down. When it reaches zero, every family phone rotates to a new code word at the same moment, without a central server in between.
Only the administrator pays. Everyone they invite is protected at no additional cost.
Pairing a word with a two- or three-digit number makes the daily code word far more unique and harder to guess than a random word. Those extra digits multiply the possible combinations, so even someone who knows your family can’t simply guess the day’s code.
Why safe words fail
Safe words or code words fail for a simple reason: families are human.
They only work if they are remembered, protected, updated, and reliably used in moments of stress. Miss one step, and your whole defense quietly stops working.
Forgotten
Chosen months ago — nobody remembers it.
Stale
The same word reused far too long.
Leaked
Overheard, or said first by mistake.
Unsynced
Not everyone has the same current word.
What experts already admit. How Family Moat closes the gap.
Every institution stops at “agree on a word.” Real life is where it breaks down. Memory fails, habits slip, and stress takes over. Family Moat’s daily code word rotation removes the human weak point.
| Where it fails | What experts admit | Family Moat |
|---|---|---|
| Family forgets it under stress | UC Berkeley’s Hany Farid: “even simple safeguards only work if people remember to use them.” | Today’s code word is always one tap away. Nothing to memorize. |
| The word gets stale or leaks | Starling Bank: “change it every now and again, and immediately if you think it’s no longer private.” | A new code word is generated automatically every single day. |
| Hard to keep everyone in sync | No bank or agency offers a way to coordinate the word across a whole family. | Every phone shows the same code word — no server, no group text. |
| The victim blurts it out first | Eva Velasquez, Identity Theft Resource Center: victims have said the safe word first instead of letting the other person say it. | Even if today’s code word leaks, it’s worthless tomorrow. |
| Setup friction | Banks tell families to “agree in person” — easy to say, rarely done. | One invite link adds a family member in seconds. |

Questions families ask
Before you trust a new safety habit.
Does Family Moat store code words on a server?
No. Code Words are generated on-device. Family Moat is designed so your family’s code words don’t live online.
What if we don’t have internet?
It still works. Because code words are generated on your device, you can verify loved ones even during outages or while traveling.
How do we use it during a suspicious call?
Ask the caller for today’s family code word before sharing money, gift cards, account details, or personal information.
Which devices are supported?
Family Moat works across iPhone, Android, and web browsers, so families can verify each other on the devices they already use.
Is this the same as a 2FA app?
It’s different. 2FA protects account logins. Family Moat helps you verify a person — especially when deepfake voice or impersonation is a risk.
What about phone-hacking spyware like Pegasus?
Family Moat is designed to stop AI voice-clone scams, deepfake impersonation, and “family emergency” fraud calls — the threats that target ordinary families every day. It is not designed to defend against nation-state spyware like Pegasus, and honestly, no app can. Tools like Pegasus run at the operating-system level with root access, so they see whatever the phone sees — inside any app.
The good news: Pegasus is overwhelmingly aimed at a narrow group of targets (journalists, dissidents, political figures, senior executives). The fraud that actually reaches most families — a panicked call from someone who sounds exactly like your child — is exactly what Family Moat is built to stop.
If you do have reason to believe you may be personally targeted, the strongest practical defenses are: turn on Apple Lockdown Mode, keep your operating system fully up to date, restart your phone regularly, and enable Apple’s notifications for state-sponsored attacks.
Recommended phone hygiene
Family Moat protects you from impersonation calls — but a healthy phone is the foundation of all mobile security. For defense against sophisticated spyware, we recommend these free steps from Apple and Google:
