HUMAN AUTHENTICATION
CoTrust replaces confusing numeric codes with three simple, spoken words — making identity verification natural, human, and impossible to fake.
New code generated every 30 seconds
SIMPLE BY DESIGN
Instead of a string of numbers that people mishear and mistype, CoTrust generates three real words — easy to say, easy to hear, impossible to confuse.
Try reading that clearly to your mom on the phone. Now again because she missed it. Numeric OTPs are designed for machines, not humans.
Three real words you can say, hear, write, and remember. Authentication that feels human — because it is.
THREE STEPS
Request a three-word code for whoever needs to verify you — or generate one to confirm someone reaching out to you is who they say they are.
Speak them aloud, text them, or read them over the phone. Three words is all it takes — no squinting, no copy-paste, no reading digits backward.
The other party enters the words and identity is verified — instantly. Clean, fast, human. No special app needed on the other end.
WHO IT'S FOR
CoTrust works both ways — verify people who reach out to you, or prove who you are to someone you trust.
Your daughter is abroad and texts asking you to wire $1,000 for an emergency flight. Is it really her? With CoTrust, she says three words — and you know for certain.
"River. Crane. Echo. It's me, Dad."
Scammers impersonate banks, utilities, even grandchildren. CoTrust gives seniors a simple way to verify who they're really talking to before sharing anything sensitive.
Stop the call. Check the words. Stay safe.
Imagine your financial advisor proves it's really them with three words only they could know. CoTrust is building toward enterprise authentication at scale — the next layer of trust.
Built for the future of financial verification.
Ask them to provide their CoTrust code before you share anything. Banks, doctors, advisors — anyone can prove themselves.
Generate a code and share it so the person you're contacting can confirm it's really you — not a fraudster pretending.
THE EXPERIENCE
CoTrust generates a fresh three-word code that expires automatically. The words are chosen for maximum distinctiveness — no "the", "and", or common fillers. Just three clear, unambiguous words.
Each code expires automatically so old codes can't be reused or replayed.
Say them in person, over the phone, or via text. No app required for the recipient.
Use CoTrust with everyone you care about at no cost, forever.
IN AN AGE OF AI
AI can now clone a voice from a 10-second audio clip. A scammer can call you sounding exactly like your daughter, your doctor, or your bank — and you'd never know.
What Terminator imagined as science fiction is today's reality. The machines don't look like Arnold. They sound like the people you love.
CoTrust gives you a shared secret that no AI can fake — because it lives only in your app, not in any audio or video a model has ever seen.
Watch the clip on YouTubeTerminator 2 (1991) — the T-1000 impersonates John Connor's mother to find him. This scene was fiction. Today it's a $15 app.
