Why this exists
Blind-ID was built out of frustration with an internet increasingly full of bots pretending to be people. Botnets, astroturfing campaigns, entire conversations with nobody on the other end.
Why the companies who do identity will not build this
It is a fair question, and the answer is not that nobody thought of it.
Almost every identity company sells to the website, not to you. That shapes what they build. They want to hold the identity, keep the data, and own the relationship with the site, because that is what they are paid for. You are the subject of the transaction, not a party to it.
A sign-in that keeps nothing is a worse business for them, and that is precisely the point. There is no data to accumulate, no profile to enrich, and no lock-in to sell. Nobody optimizing for the other model would ship it, which is why the space is open.
Why not use "Sign in with" a big platform
Those buttons work, and they are the thing this is most often compared to. The difference is what sits behind them. A platform login is an account that can be fake, can be one of thousands, and is visible to that platform across every site that uses it. A Blind-ID sign-in is backed by a government ID, and the code each site receives is visible to that site alone: not to other sites, and not to us, because we do not keep it. There is no account to create, nothing to remember, and nothing that follows you from one site to the next.
What this is instead
- Something small and purpose built, where the limits are obvious and stated.
- Something technically understandable and transparent, not a black box.
- Clear control over what is shared, decided by you in your own wallet, every time.
- No intrusive face scans. No uploading photos of your license or passport to a stranger's server. Wallets already do this properly: they tell you exactly what is being asked for and make you approve it. People trust that, and they are right to.
Plenty of verification services collect far more than they need and keep it indefinitely. Rather than ask you to believe this one is different, the design removes the question: there is nothing to misuse, because the information is never held in the first place.
What is the catch? How does this make money?
The sites pay. Signing in is free for the person doing it and always will be, and a site gets a generous free allowance. Beyond that, sites pay for sign-ins and for age checks, which is where very few people are comfortable doing a face scan to prove they are an adult. Nothing about you is sold, because nothing about you is kept. That is what makes the promise worth anything.
If you cannot work out how a free service makes money, the usual answer is that you are the product. Here you are not, and the actual plan is set out above rather than left as a gap for you to fill in.
Why not keeping your data is the point
Beyond principle, holding personal data is a liability. It carries legal obligations that differ by state and by country, breach exposure, and audit burden. Since none of it is being sold, that risk buys nothing. Not collecting it is both the honest choice and the cheap one.
What if law enforcement asks for information?
Then there is very little to hand over. Nothing about you is kept, and nothing we hold says which sites you use. What exists is each site's own sign-in log, held for the site, with the IP address your browser came from, retained to detect and stop abuse of the service, and the site's own identifier for you, which says nothing to anyone else.
That is a deliberate compromise rather than an oversight. A service like this could otherwise be captured for genuinely harmful purposes, and keeping a single thread to pull on makes that far less attractive without handing over anything about who you are. If you would rather not share your IP address with this site at all, there are many well established ways to mask it, and nothing here depends on knowing it.
What is committed to, and what is not
A few commitments that can actually be kept, rather than a long list to be quietly walked back later.
- Signing in with Blind-ID stays free for the person doing it.
- Nothing is shared without you seeing it and approving it first, in your own wallet, every single time. That is the commitment everything else rests on.
- Nothing read from your ID is kept, and nothing we hold connects you across sites.
Deliberately not promised: that every future feature will work exactly this way. Anything built later that involves your information differently will be optional, will say plainly what it does, and will be something you choose knowingly. The guarantee is transparency and consent, not a blanket vow about a future nobody can see far enough into.
