The Problem

You can't trust what you hear or see.

Modern scams are frighteningly convincing. Traditional ways of verifying identity over the phone no longer work.

AI Voice Cloning

Scammers can clone anyone's voice from just a few seconds of audio. Your mom, your boss, your bank - all perfectly imitated.

Caller ID Spoofing

Phone numbers can be faked. That call from "Dad" might not be from Dad. Caller ID alone can't be trusted anymore.

Text Message Scams

SIM swaps and number hijacking mean a text from a trusted contact could be from someone else entirely.

Video Deepfakes

AI-generated video is getting more convincing by the month. A familiar face on a screen won't be proof of identity for much longer.

In Action

Two words. Mutual trust.

Each pair of contacts has two different TrustWords - one for each direction. A scammer can't fake both sides.

Real call from Mom
Hey Mom, what's your TrustWord for me?
It's mellow-rabbit-94. Now what's yours?
swift-aurora-66. We're good! So about Thanksgiving...
Both identities verified
Scam call pretending to be Mom
Hey Mom, what's your TrustWord for me?
What? Honey, it's me! I need you to send money right away, it's an emergency -
What's your TrustWord?
I... I don't remember, please just -
Scam detected - hang up

The Solution

An automatically rotating code word, unique to every relationship.

The FBI recommends families agree on a code word to verify identity over the phone.

TrustWord takes that idea further - instead of a static word that could be guessed, overheard, or leaked, it generates a unique passphrase for every pair of contacts that changes automatically.

Step 1

Create a Circle

Group the people you want to protect - family, close friends, anyone you might need to verify.

Step 2

Scan Each Other's QR Code

A one-time, in-person exchange. After that, TrustWord handles everything automatically.

Step 3

Ask for the Word

Get a suspicious call? Ask them for their TrustWord. Check it against your screen. If it doesn't match - hang up.

TrustWord is 2-Factor Authentication for people

Who It's For

Protect the various circles in your life.

Families

Elderly parents are the #1 target of voice cloning scams. Set up a circle with your family so anyone can verify a suspicious call in seconds.

Friends

Got a strange call from a friend asking for money? One quick question tells you whether it's really them.

Colleagues

CEO fraud and business email compromise cost billions annually. Give your team a simple way to verify urgent requests over the phone.

Features

Security that gets out of your way.

Built with the same cryptographic standards used by authenticator apps, but designed for real people having real conversations.

Rotating Passphrases

Codes change every 2.5 minutes. Each pair of people sees their own unique phrase - no sync needed, no shared secrets.

Biometric Protection
