Your codes.
Your phone.
Nobody
else's server.

Most authenticators keep your codes on a company's servers. zeroKey doesn't. They're saved somewhere nobody owns — so they keep working even if we don't.

▌ HOW IT WORKS

Three simple ideas. One safe app.

No accounts. No passwords. Your phone is the key — and a copy of your safe is always somewhere we can't touch.

01 / YOUR PHONE

A key only your face can use.

When you set up zeroKey, your phone makes a secret. It never leaves. It only works when your face unlocks it.

setting up
→ saying hi to your phone...
→ asking for your face...
done
only you can open this
02 / YOUR SAFE

Your codes turn into nonsense.

Every code you save gets scrambled into bytes that look like static. Without your face, the safe is unreadable — even to us.

// what it looks like to anyone else
{
  site:   "████████",
  code:  "████████",
  noise: "7f4a9c2e…"
}
// gibberish without your phone
03 / FOREVER

Your safe goes somewhere we can't reach.

The scrambled bytes get saved to a public place that nobody owns. Lose your phone? Get a new one, prove it's you, and your codes come back.

location: public, permanent
who can read it: only you
who can delete it: nobody
done — for good
▌ WHY IT'S SAFE

If we vanish tomorrow, your codes still work.

We didn't build a service you depend on. We built something you own. There's no plug for us to pull.

Only you can see them

Your face is the only way in. Not even we can look.

Your face is the password

Nothing to forget. Nothing to type. Nothing to lose.

All your devices, one safe

Phone, tablet, spare — they all open the same codes.

Re-locked every time

A fresh lock on every change. Old copies become useless.

Nobody knows it's yours

No name, no email, no profile. Just your codes.

Works without internet

Codes show up on the plane, in tunnels, in the woods.

Lost phone, no panic

Mark it gone from any other device. Codes stay yours.

Free, forever

No upsell, no premium, no bill. Was, is, will be.

▌ HOW WE STACK UP

Other authenticators have a quiet problem.

The easy ones depend on a company. The safe ones leave you stuck when your phone breaks. zeroKey is both easy and safe.

▌ COMMON QUESTIONS

Things people actually ask.

Do I need to know anything about crypto to use this?
Nope. Sign in with your face. We handle everything else behind the scenes. Most people use zeroKey for years and never know what's underneath.
What if zeroKey shuts down?
Your codes keep working. The place we save your safe to is public and permanent — anyone can build a new app to open it, including you. We're not a service you can lose.
Why not just use iCloud or Google to back up?
Those are great — until something happens. A locked account, an outage, a country block, a leak. zeroKey doesn't have any of those single points of failure. Your safe doesn't depend on one company being okay.
Can people see what apps I use?
No. Your safe is a wall of scrambled bytes. The names of the sites, the codes, all of it — locked inside, only readable on your phone.
What if I lose my phone?
Get a new one, prove it's you (a backup phrase, a paired device, or a written recovery code — your call), and you're back in. Your safe was never on the lost phone in the first place.
Is it really free?
Yes. There's no premium tier and no upsell. We don't run servers, so we don't need your money to keep running.

Take your codes
into your own hands.

Free. iPhone now. Android this summer.
