The moment
01
No popup. No overlay. No widget on the page — by design.
02
An approval request that lives ten seconds. Face ID. That's it.
03
Fields fill themselves. You move on. The credential never touched your keyboard.
Quantum-resistant by default
Your vault is sealed with AES-256-GCM — encryption that stays strong even against a quantum computer. As cross-device sync arrives, key exchange uses ML-KEM (the NIST post-quantum standard) on iPhones running iOS 26 and later.
Authenticated encryption that resists quantum attacks — on every supported iPhone, today.
We store ciphertext. We never see a key, a password, or a session.
The Master Key never leaves your phone. Biometric unlock — no master password to phish.
More than passwords
Passports, ID cards, recovery codes, private notes, banking documents. The same biometric ritual unlocks them. The same zero-knowledge model protects them.
Shared with family when you choose. Gone when you choose.

What lives inside
Every item in Kyber is encrypted on your phone, before it ever moves. The same Face ID unlocks them all.
Auto-filled on iOS by the system. Never typed.
FIDO2 / WebAuthn — generated, stored, used. No popup.
Numbers, CVV, billing. Pasted only when you ask.
Passport, ID card, driver's licence. Photo and fields, both encrypted.
2FA backups, crypto wallets, BIP39. The vault you actually trust.
Anything else. License keys, door codes, wills. End-to-end encrypted.
iCloud sync arrives in 1.0.1. Until then, your vault stays on this phone — guard your recovery phrase.
Pricing
Kyber 1.0 ships free on a single iPhone. Cross-device sync, sharing and unlimited items arrive with the first update, as a paid tier — same price as the competition, none of the data.
Everything that matters, on the device in your hand.
Available at launch
A Pro tier with unlimited items, iCloud sync and family sharing arrives with the first update — €2.99/mo or €24/year. We'll tell you the day it ships.
No tracking pixels. No ads. No data sold. Ever. Audited annually under EU sovereignty rules.
Questions
Kyber generates a unique credential per site, stores it encrypted on your phone, and uses Apple's AutoFill system to type it into iOS apps and Safari for you. You see Face ID. Kyber sees ciphertext. The website sees the password — exactly as before.
Your vault is encrypted with AES-256-GCM, which stays secure even against a future quantum computer — that protection is live today, on every supported iPhone. When cross-device sync ships, key exchange will use ML-KEM (the NIST post-quantum standard) on iPhones running iOS 26 and later. We say exactly what's built and what's coming — no more.
No. The master key never leaves your Secure Enclave. Even if our servers were seized, all that's there is ciphertext we cannot decrypt. Zero-knowledge isn't a marketing phrase here — it's a constraint on our own engineers.
During setup, Kyber gives you a 24-word recovery phrase (BIP39 standard). Write it down. Lose your phone, restore on a new one with that phrase, your vault is back. Lose both the phone and the phrase, and we cannot help you — that's the price of zero-knowledge.
Three things: (1) invisible UX — no popup, no widget, the phone vibrates and you're in. (2) Quantum-resistant storage today, with a clear ML-KEM roadmap as Apple's platform support matures. (3) EU-based and EU-owned, no US legal exposure. We're not 'as good as' — we're a different bet.
In version 1.0: locally on your iPhone, encrypted with a key only your face can unlock. From 1.0.1: optionally synced to your iCloud (still encrypted, Apple can't read it either). Never on our servers.
You shouldn't — yet. That's why the 24-word recovery phrase exists, why the code uses standard primitives (no homegrown crypto), and why the architecture is auditable. Trust is earned. We're starting.
