Identity ยท iPhone
Kenni
Know who's really there. Even when a voice can be faked.
Cryptographic identity checks against scams and AI impersonation. Free and open source.
A look inside
A voice can be cloned. A KENNI confirmation can't.
AI can imitate the people you love, chat like your boss, and fake any face. KENNI lets the people you actually trust prove cryptographically that it's really them. One tap, one signed answer, no doubt.
Three steps, then certainty.
- 1
Exchange keys once
Meet face to face and scan each other's QR code, or share a one-time link. Your devices now hold keys that no server ever sees.

Something feels off?
A call, a chat, an email asking for money or a code. Open KENNI, tap the contact, and send a silent check.

They prove it's them
Their phone asks: "Is this really you?" The answer is signed by a key only their device holds, so it can't be faked. No internet? Spoken 6-digit codes work too.
Built to be trusted, not just used.
No accounts, no phone number, no email. Your identity is a key that never leaves your device, and it's all open source, so anyone can check the claims.
