Kin Pass
In short A one tap replacement for image puzzles. Sites learn that a real, unique person is here, and nothing more; in development.
Image puzzles were built to stop bots. Now AI solves them faster than people do. Kin Pass replaces the puzzle with one tap that only a verified human can make. It is in development.
Why the old check is broken
- AI solves the puzzles. Modern image models pick out traffic lights, crosswalks and bicycles as well as any person.
- People pay the price. Real people squint, fail and try again; many give up and leave.
- Privacy pays too. Some checks decide who is human by watching how people move and browse.
How Kin Pass works
A site adds the Kin Pass widget to a form: sign up, login, comments or checkout. A visitor taps once and confirms in Kin ID. The site's server receives a signed answer, a real and unique person is here, and checks it with one request.
| Puzzle checks | Kin Pass | |
|---|---|---|
| What people do | Solve puzzles, often more than once | Tap once |
| Against modern AI | Weaker every year | Only verified humans pass |
| What the site learns | Often behaviour and browsing | One answer: a real, unique person |
| Accessibility | Hard with low vision or a slow connection | One button, in 19 languages |
Kin Pass and Kin OAuth
Kin OAuth is for apps that want an account system built on proof of human. Kin Pass is for sites that only need to stop bots at a single step and do not want to know anything about the visitor at all. Both use the same checks and the same privacy promise.
Fallback
During the beta, sites can keep their current check as a fallback for visitors who do not use Kin ID yet, so nobody is locked out.
Timeline
A private beta with partner sites is planned for early 2027, and Kin Pass is planned to open to every website later that year.
