Someone says they're your daughter, your father, your accountant, your bank. zikora checks, in under a minute, using a key on their own phone. No passwords. No security questions. Nothing to guess.
A phone number can be spoofed, a voice cloned, an email header forged. Whatever the medium, it delivers a statement about who someone is, and no way at all to check it.
Cloning a voice takes three seconds of audio.
Right name, new number, no way to ring back and check.
The right firm, the right tone, the wrong account number.
Three channels, three people you actually know, one shape: somebody asserts an identity, and nothing about the way it arrived can confirm or deny it.
Choose the person they claim to be. zikora makes a fresh phrase for this call and this call only — never reused, gone in minutes.
Read the phrase to your caller. Anyone can hear it; only one person in the world can answer it.
Their device signs the phrase with a key only they hold. Your screen flips to verified — or it doesn't, and now you know.
A safe word you must whisper can be overheard, guessed, or tortured out of someone. zikora's phrase is said out loud to the fake and the real alike, and only one of them can answer it.
A forged answer is rejected. Yesterday's answer is useless. And doubt never quietly becomes trust: a challenge expires in minutes, visibly, and expiry is not a verdict.
Under the hood: each person holds an Ed25519 key on their own device, created by their phone's own passkey. zikora never holds it, and there is nothing in the middle to steal.
