    From my understanding this age verification app seems to be based on the age verification blueprint they have been working on for a while now, which is supposed to be part of the European “digital wallet”

    https://digital-strategy.ec.europa.eu/en/policies/eu-age-verification

    From my understanding it works as follows:

    • There will be a central “authority”, with which you can identify
    • This authority will provide you with tokens indicating you are 18+ (or whatever age verfication you may need)
    • These tokens are stored locally, and contain no identifying information other than a simple “is this guy 18+?”
    • You can use these tokens to verify age with a website that requires age verification

    This solution does seemingly address my two greatest concern with online age verficiation:

    • You cannot trust the website, so they only get the information they need. They don’t get any identifiable information
    • You cannot trust the authority, so they don’t get to know for which websites and for what reason you request 18+ tokens

    Assuming that this blueprint is followed, it seems like a decent approach at online age verification.

      This authority will provide you with tokens indicating you are 18+ (or whatever age verfication you may need) These tokens are stored locally, and contain no identifying information other than a simple “is this guy 18+?”

      So they’re reusable? One token can be used for multiple age checks, right?

      If not, then think about what that means.

      1. The token gets sent back to the authority for revocation.
      2. The token is authorised by the central authority as still valid.
      3. The token is uniquely identifiable
      4. The central authority knows who it issued each token for
      5. The central authority knows who has asked it the verify age.

      Sure, the company you’re purchasing from may have no new information, but the central authority now has everything it needs to know:

      • How often you buy tobacco, alcohol or medications
      • What discussion boards you are a member of
      • Have you purchased anything age restricted from any store (e.g. propane from a DIY store)

        Not sure that’s necessarily true. I don’t see why it couldn’t work like this:

        1. request personal token from authority. it works similar to a certificate chain, your token is derived from a central certificate
        2. you store your token locally
        3. you visit an age-restricted website. you send your token (or a challenge encrypted with that token) back to the website
        4. the website verifies your token with the certificate from the authority, (like how literal Certificate Authorities work) . the CA doesn’t know when or why your token was used.

        (fwiw I am sure governments will try their best to make this process less private)

          Your step 4 will make the token reusable, or at least reusable within a time frame. If a token can only be used once there has to be some information flow back to a central approval authority.

      I get why this sounds better than websites directly collecting IDs, but I think it still understates the problem. Even if the site only sees “18+”, the system still begins with strong identity proofing somewhere upstream. So this is not really anonymous access, it is identity-based access with a privacy layer on top.

      The bigger issue is centralization. You still need trusted issuers, approved apps, approved standards, and authorities deciding who can participate. That means users are being asked to trust a centralized framework not to expand, not to abuse its power, and not to fail. History gives us no reason to be relaxed about that.

      I am also skeptical of the privacy promises. These systems are always presented in their ideal form, but real-world implementations involve metadata, logging, renewal, compliance rules, vendors, and future policy changes. “The website does not know who you are” is only one small part of the privacy question.

      So even in the best-case version, this is still dangerous because it normalizes the idea that access to lawful online content should depend on credentials issued inside a centrally governed identity ecosystem. Today it is age verification. Tomorrow it is broader permissioned access to the internet. That is why I do not see this as a decent compromise, but as infrastructure for future control.

        I do see your concerns as valid. But at least in my country, we already have all of that.

        I have an app I use to id myself to all sorts of stuff. Almost all of us has that. All the changes you mention are not changes, we have already had that for years. The new thing is that you don’t give your id to the website.

        Just like during the pandemic, we had an app to prove our vaccination status, without revealing id. Before that we had to prove id, and then they looked up vaccination status.

        As far as I understand, there’s no need for “verified apps”. The third party just verifies your token with the emitter.

        The skepticism is very understandable. It is important to scrutinise solutions like this to make sure that they indeed do as they say they do, and to make sure the government doesn’t overreach with their authority.

        That said, it should also be possible for laws to be enforced, and there are laws on the books that are supposed to prevent children from accessing things that we as a society have agreed they have no business accessing (alcohol, tabacco, porn, and increasingly commonly social media)

        Currently there is no good method to actually enforce those laws on the internet, so there needs to be a solution for that.
        I think this form of age verification may be a decent compromise between privacy and the need to enforce these existing laws.

        Edit: Typo. I wrote “they” instead of “that”

          there are laws on the books that are supposed to prevent children from accessing things they we as a society have agreed they have no business accessing

          The problem is that different societies have different lists of things that they deem children shouldn’t access (or in some cases, citizens in general). For instance, conservative-leaning U.S. states are increasingly labeling any and all LGBTQ content as being unsuitable for children, furthering their indoctrination against a persecuted minority group.

          Parents are in the wrong for preventing their children from accessing content depicting LGBTQ perspectives, and age verification tools in such markets are likely to be designed with the express intent of blocking access to LGBTQ content for minors by default.

          I think the disagreement comes from treating “we have laws” as automatically meaning “we must enforce them everywhere at any cost.” The method matters. This approach flips the burden of proof by treating everyone as a minor unless they prove otherwise. That is a pretty extreme shift from how things normally work in the real world.

          We also shouldn’t pretend this actually solves the problem. Kids got access to adult magazines before, and they will get access now through a parent’s phone, shared devices, or older friends. If that’s the target, this kind of system is mostly symbolic while adding friction and control for everyone else.

          And more importantly, it normalizes something much bigger. Once you accept that accessing legal content requires proving attributes through some approved system, it becomes very easy to expand that logic. Today it’s age. Tomorrow it can be anything else.

          So I don’t see this as a balanced compromise. It’s a disproportionate response to an enforcement gap, with long-term consequences that go way beyond the original problem.

            I don’t think laws should be enforced at any cost, but if we can reasonably enforce laws I think there is a duty to do so.

            Then there is also a different question of whether we agree with the laws on the books, but that is a different matter imo. Personally I don’t think we should limit access to pornography as strictly as the laws says we should, and I don’t think the ills of social media are solved with a simple age limit.

            But that is a separate discussion from the implementation of a (in my eyes) reasonable approach to age verification

              I don’t think it’s entirely a separate issue, because how a law is enforced is part of evaluating whether it makes sense in practice.

              If a law can only be enforced by treating everyone as a minor until proven otherwise, that’s a strong signal that the law, or at least its scope, may be flawed.

          Protection from media at the government level should not happen, that’s the slippery slope. Very few policies aside from educate children about topics, has ever actually helped a child. This shit is about data and overlord control. Devices should not have age verification.

          Very little good comes from arbitrary control, particularly based on age, and always has been that way even on other topics that are age restricted. Education is a far more effective means, and doesn’t trample everyone.

        I don’t see a central authority (i.e. your government) issuing tokens, as much different from the government issuing you a ID card by which you can verify your age to buy alcohol in the supermarket.

        As long as that central authority doesn’t get to know what I use the tokens for, it seems like an acceptable solution to me.

          Too me one of the big issues is being able to trust a government or business to not trace a person’s identity back through the token. There are technical ways to prevent that as far as I’m aware, but there’s such a strong incentive against such protections that it’s really hard to trust unless you’re technologically skilled enough to verify the process yourself.

          The difference is in the potential for creep.

          The proposed implementation would actually be less invasive than a national ID card (assuming the implementation information provided is complete and accurate), but also usable in less scenarios.

          AFAICT there is no provision for actually verifying the person using the app is the person who’s identity is verified in the app.

          What’s to stop one person having a verified identity and just sharing it with the people around them once it’s been issued ?

          As an example, with an ID card in a bar you need to match the photo, this digital system would be like turning up to a bar with an ID that had no picture or details on , but just said “over 18”, you could then hand this to a friend and they could also use it.

          I personally think that if a system is mandatory then an easily circumventable verification system is the best choice , but such an easily circumventable system is exactly the kind of thing governments have used as an excuse to push for further encroachment.

          Take the UK for example, the online safety act they have is easily circumvented with a VPN (which many people noted before it was implemented) the government basically stuck their head in the sand and claimed vpn’s weren’t widespread enough to be a problem.

          Skip to now and they’ve got representatives looking to force vpn compliance with the online safety act without having the slightest clue about why that wouldn’t and can’t work the way they want.

          A more suspicious person might suspect the attack on vpn usage was an expected part of the overall plan.

          Even a less suspicious person could still see the direct line from one to the other.

          I’m not saying they will, but if i were a betting person, I’d certainly put some money on it.

      On one hand this is an elegant solution that is already in use in Germany for years, if companies want to implement it that is. But I think only Sony’s Playstore uses it. Or so I have heard. No US company wants to use it and I am sure they will lobby to get more data from users than a token if this gets rolled out EU wide. I am skeptical about this.

      Could even have an OAuth flow that only provides a service unique key that the service can use to call the central authority to confirm the user is 18+ and nothing else, I always thought this would be the second best solution
