Cloned voices
A few seconds of audio is enough to recreate almost anyone's voice — pleading with you, on the phone, in real time.
Mutual human verification
Are you really talking to who you think you are?
Scammers can now clone a loved one's voice, spoof their number, and deepfake their face. Human OTP gives you and the people you trust a matching code that proves, in seconds, that it's really them — on any call.

The person on the other end may not be a person at all
AI made impersonation cheap, fast, and terrifyingly convincing. The tells we used to rely on — a familiar voice, the right number, a face on video — no longer prove anything.
Spoofed numbers
Caller ID is trivial to fake. The screen can say "Mom" or "Your bank" while a stranger is dialing.
Deepfake video
Live face-swaps put a trusted face on a video call. Seeing is no longer believing.
This isn't hypothetical — it's how "grandparent scams," fake-boss wire fraud, and family emergencies-that-never-happened work today.
Why "just use a code word" fails
Secret family passwords sound great — until you need one
Everyone's advice is the same: agree on a secret word with your family. In practice it falls apart the moment it matters.
- You forget it under stress — exactly when a scammer is counting on panic.
- Say it out loud once and it's burned — anyone listening now has it forever.
- It's awkward to demand a password from your own mother.
- It never changes, so one leak compromises you permanently.
Pair once. Then both phones always agree.
No memorizing. No typing. A code that lives on your devices, rotates every 30 seconds, and can't be guessed or reused.

Pair in person
Sit down together once and scan each other's QR code. That's the whole setup — a shared secret passes phone-to-phone. It never touches a server.
-
2
Both phones show one code
From then on, each phone independently shows the same 6-digit number and emoji sequence — refreshing every 30 seconds. No internet required.

Read it aloud on the call
When something feels off, ask them to read their code. It matches yours, or it doesn't. Real, mutual proof — in about five seconds.
It goes both ways. You verify them and they verify you. Each of you reads a code the other confirms — so no one has to take anyone's word for it.
Built-in safety
A panic code, hidden in plain sight
During a verification you read your code aloud. If someone is forcing your hand, press and hold your code to reveal a second one — your panic code — and read that instead. To anyone watching, nothing changes. But the person on the other end sees a quiet, unmistakable signal that you're in trouble.
- Same calm screen, same routine — nothing an onlooker would notice.
- Their app flags duress silently: no alarm, no banner, no sound.
- Works with anyone you've already paired with — no extra setup.
A signal only the two of you can read. Ready the moment you pair.
Your secrets never leave your phone
There's no account to create and no server holding anything about you. The trust lives on your devices — full stop.
Works offline
Pairing and verifying need no connection at all. It works on a plane, in a basement, anywhere.
No accounts
No email, no phone number, no sign-up. Nothing to log in to means nothing to breach.
No servers hold secrets
Shared codes live only in your phone's secure storage — never uploaded, never backed up to us.
Nothing to track
No analytics on your contacts, no profile of who you talk to. It simply isn't collected.
