No password to phish
There's no password and no central vault of secrets. The thing attackers go after simply doesn't exist here.

Why it's different
Built so there's nothing to steal.
Real humans, no bots
A three-second liveness check gates sign-up. Your photo never leaves your phone — only a one-way math fingerprint does.
Yours alone
Your key is generated and sealed inside your device's secure hardware. Every post and message is signed by you.
The idea
Passwords leak. Companies get breached. Bots flood the gates.
So we removed the thing that gets stolen.
No password to phish. No vault to raid. Just math you carry, and a network of real, vouched humans.
