One key. Every Kronos door. Sign-ups are not open yet — on purpose.
This page is what you will be joining, written down before you can. Nothing to sign.
What it is
A KronosID is the single account you hold across every Kronos place. Make it once. Every door we build after that already knows you.
No second sign-up when a new place opens. No third password. No “link your accounts” screen, because there is only ever one account. Your name, your standing, your preferences and your card all live in one identity that you hold — and each place asks it only for what that place needs.
It is ours. We built it, we run it, and it is the same team behind every place it opens. That is the point of it: when you walk into the next Kronos door, you are recognised, not interrogated.
The doors it opens
One lamp is lit. It is the door KronosID opens with. The rest follow, and each one will be announced here before it opens, not after.




How you will sign in
When the door opens you can make a KronosID with your Google or Apple account — they prove your address, so there is nothing to verify and no new password to invent. Or use an email and a password of your own. Either way it is one KronosID; you can add the other later from your own security page, and unlink it just as easily.
One rule under all three: every KronosID has an email address. It is where a reset goes and how we reach you, so Google or Apple alone is never enough on its own — they just save you the typing.

And then, the card
A physical card carrying your KronosID on a DESFire chip. Tap it on a Kronos reader and you are in — no screen, no typing, no phone in your hand.
Here is the honest part, because it is the clever part. The name on a card is a claim; anyone can print one. The tap is the proof: the reader and the chip run a mutual cryptographic handshake, and a copy with a different chip fails it. Nothing is read off the card and trusted. It is challenged.
And rights follow the identity, never the plastic. Lose a card and it is replaced; you are not. The first cards already exist and are in our own pockets. Yours comes after the door opens.

Security, said plainly
Most of what makes an identity safe is boring and should stay that way. Here is the part you would want to know:
Google and Apple prove your address to us. The card proves its chip to the reader. We never take a name at its word.
Signing up to meet people opens nothing else in your name. Each place asks for what it needs, when it needs it, and you say yes.
If a Google account and an email address turn out to be you, we ask you to prove it once. Two accounts are never quietly glued together.
See every device signed in, sign one out, or all the others. Linked accounts can be unlinked. Standard, and yours.
Why
We are building places, not feeds. A quarter with a floor. A room that follows a show. A writers’ table. Places you go, at an hour, where the other people chose to be there too.
Every one of them needs a way to know it is you at the door, and we did not want that to be the dreary bit. So it is one key, made once, that you can hold in your hand. Then the fun can start on the other side. That is the whole idea: bring a bit of joy back to walking in somewhere.
Today, 4 September 2026
No form, no newsletter, no cookie banner because there are no cookies. No tracker, no pixel, no script at all. The only things this page asks the internet for are its own pictures.
This address does hold the KronosID sign-in door, for the handful of us who already carry one while we build. Behind it, a sign-up is refused today — by the server, not by hiding the link.
You will know where the door is when it opens. It is this one.
