Voice, Video, Images, and Texts Can Be Faked.
Private Codewords Can't.
Trust Onion gives your family, friends, or club three rotating private codewords that stop AI scams cold. If they can't say the words, it's not them.
We have parents, grandparents, and siblings we don't want to be scammed.
We built a private way to verify identity in seconds, no technical skills required.
Core features that keep your circle safe
Every feature was built for one thing: giving you a fast, private way to verify the people you love are who they say they are.
Verify in three words
Your codewords rotate every 60 seconds and are calculated locally on each device. No server, no internet required.
Prove it in a photo
Request a live selfie from anyone in your circle. AI-checked for freshness, delivered instantly.
Create a family account in seconds
Set up a private family circle in under a minute. Invite only the people you trust with a one-tap code or QR scan, and keep parents, grandparents, and kids protected from AI scams; no one else gets in.
Right inside iMessage
Send your codewords in under five seconds without ever leaving iMessage. The native app lives right inside your conversations, so verifying a loved one is as quick as sending a text.
Already on a suspicious call?
Two tools that help you figure out what's happening and get your family involved. No one has to handle a scary call alone.
Scam Check
Tap what's happening on your call. Money requests, pressure to keep secrets, someone claiming to be your bank. The app tells you how risky it is and what to watch for.
Reach Your Family
Pick someone from your family circle and send a one-tap alert asking them to call you right now. They see your note and know you need them.
Coming soon: add phone numbers to your family circle. When a call feels wrong, tap a name and the app dials them directly.
Three steps. That's it.
Trust Onion fits into the way your family, friends, or club already communicate. No new habits, no complicated setup.
Open the app
Download Trust Onion and join your family group with a QR code scan. The app generates rotating codewords that only your group can see. No accounts, no passwords.
Use it when it matters
Urgent call from your kid? Ask for the word. They say it, you know it's them. They can't, you hang up and call them directly.
Add a photo for extra proof
For higher-stakes moments, request a live selfie. The photo is timestamped and checked so you know it was taken right now, not pulled from social media.
