Is there a reason why all the services, that use the ActivityPub protocol don’t have a unified API?

None of the mastodon apps allow me to log in with a lemmy/kbin account.

Also none of the lemmy apps allow me to log in with a kbin account.

Even though kbin has both mastodon (microblogging) and lemmy (threads, communities) functionality.

Also, Pixelfed recently introduced “login with Mastodon”, but all it really does is just create a new user on it’s instance and copy over the mastodon followers and profile info.

Why can’t we just have one account to rule them all?

    I’m not an expert, those who know more, please correct me.

    Regarding logging-in with one account into another instance, I think that’s not how it’s intended to work. But I’m oot sure I understand what you’re asking.

    Regarding the unified client API, 2 days ago Manton Reece (Creator of Micro.blog) wrote a response to Dave Winer’s open voicemail in where he says:

    There is a lot of work to do, even outside of ActivityPub. As Dave mentions, we also need a common posting API. The most popular Mastodon client apps do not support either ActivityPub or Micropub. But a lot of progress can be made focusing on interoperability for the server-to-server part of the API. That should be the top priority with Threads set to join the fediverse.

      logging in with one account into another instance

      I’d imagine a OAuth/JWT-like workflow, where pixelfed.social can ask a kbin-API whether my user exists on kbin.social.

      If it does, I should be able to post images on the pixelfed app that show my username as @adonis.

      Edit: by @adonis, I mean adonis @ kbin.social

        If it does, I should be able to post images on the pixelfed app that show my username as @adonis.

        It cannot work as stated because there could be another @adonis accounts in other instances and the only way to prevent that would be to centralize all the signups which goes against the whole idea of decentralization. That’s why the user must be @adonis1@kbin.whatever as it is shown now.

        Regarding the OAuth/JWT, again… not an expert, but what I understand is that that kind of integration is much stronger than the current system. AFAIK, it could work as you say, but that would make things much more complex for the servers; you usually provide OAuth authentication for a few services, I don’t know how well that scales with … hundreds / thousands (?) of authentication provders. But, who knows, maybe in the future it’s implemented in one way or another.

        We should take into account that this technology is fairly new and people are still building on it.

          Sorry but the autoformatting miscommunicated my statement… by @adonis I meant adonis @ kbin.social.

          And the domain is always part of the actual userhandle. Hence, there can only be one.

          Regarding OAuth/JWT, these aren’t new concepts. They’ve been around for while, if not decades.

          Why would there need to be a signature to every post? According to your statement, any service that provides OAuth/JWT would be prone to this fatal flaw, wouldn’t it?

            No, because the model for ActivityPub is very different than how OAuth is used for authentication. What you describe is like wanting to log in to hotmail using your gmail account, and being able to send and receive e-mail from your gmail address.

            It is a fundamental to ActivityPub that a user exists at a domain, and content coming from or going to that domain is sent from / to the relevant server at that domain.

            Federated login is a good idea, and it’s been done, both in closed and open forms. Combining federated login and federated ID over ActivityPub would fundamentally change ActivityPub.

      yeah… and all it really does is create a new pixelfed account, while copying over the mastodon bio and followers.

      With extensive work, these tools can all be made to work together under a single username. Every tool needs to be made aware of every other tool, and a lot of the actual federation code needs to be externalised to an all-encompassing server. This can be done without breaking any spec and without becoming incompatible with the rest of the Fediverse, but it’ll require a LOT of work.

      You basically summarized my original plan for communick. The basic idea is:

      1. Take the existing services, provide commercial hosting
      2. Use the revenue to fund development of protocol-level integrations, contribute back to open source
      3. Build tools to make it easy for companies to migrate away from Facebook/Twitter/Instagram/WhatsApp and own back their internet presence again
      4. ???
      5. Profit / Destroy Big Tech.

      Unfortunately, the amount of people willing to pay for commercial providers of social media is embarrassingly small, so I am stuck at step 1 and the best I could do is to build a SSO system for Matrix/Mastodon/XMPP, to let people use the same credentials on all “communick.com” servers.

          imagine tech brand like LTT coming in with a federated forum for customer/community interaction

          Exactly! This also applies for old media as well. Why is it that the NYT, WaPo, WSJ, Deutsche Welle, Globo, Telemundo, Forbes et caterva haven’t still set up their own AP servers? I guess they seem as more interesting to go to Twitter and bitch about Elon Musk instead of just emptying the platform? Why can’t they become providers of a service and say “all subscribers get a free account”?

            Currently, the entire Fediverse is equal to what, two percent of Twitter’s userbase? Maybe 10% if you take out all the Twitter bots? Twitter is used for outreach, but with nobody to follow you, there’s no incentive for companies to join the Fediverse.

            This can change once some social media with actually relevant user bases start joining the network (Threads, Tumblr) but until then I wouldn’t expect any companies to bother.

            I don’t think it’d be a good idea to put journalists on an instance with their publication, though. Sure, they should use the verification feature Mastodon provides, but you don’t want a journalist’s socials to be in the hands of their boss.

            Complaining about 𝕏 makes sense for as long as there are more active people on there than there are on any of their competitors. People don’t want Twitter do die and wither away, they want it to go back to the way things were before mister “make se𝕏ual assault cases to away by giving her a horse” took over.

              I’d honestly say it’s even less and I’d even wager that the amount of bots here are even higher (percent-wise) than Twitter. I’m working on a search engine for the fediverse now, and I was surprised with the amount of bot accounts and mirror servers that I am finding.

              you don’t want a journalist’s socials to be in the hands of their boss.

              I feel quite the opposite. If a journalist is really independent, then they can go on to host their own content. But as long as they are writing under the editorial guidelines of some larger institution, I want this association to be well defined and transparent.

              People don’t want Twitter do die and wither away.

              I am fundamentally opposed to any ad-funded business. I honestly believe that moment a lot of the issues in our society can be traced back to the moment that we made it possible for people to make a living by just collecting eyeballs instead of focusing on quality work at a small scale. So, yeah, I very much want Twitter/Facebook/Google to die and wither away.

                My limited view on the Fediverse makes it seem very human operated, but I’ll trust your judgement given your experience in these matters. I don’t trust the statistics (2 million active Lemmy users, but Lemmy feeds drying up after two or three pages? No way!) but the accounts I do see just feel more genuine, I guess.

                As for journalists, verification is key. I haven’t seen any journalist that wouldn’t voluntary write the publication they work for in their bio. Mastodon provides a way to verify your relationship with an arbitrary web page (i.e. https://news.example/people/f.m.lastname) by providing a special value in the page HTML, regardless of what server they’re on. I think that would be an excellent solution.

                I agree with you on ad based services, but I don’t think we’re in the majority here. No matter how much people complain about ads and tracking, they just don’t want or can’t afford to pay for the services they’re using. This only leave predatory money making tactics if you want to make money off the content you create. When 𝕏 dies a slow death, Bluesky’s enshittification will begin.

    Because they are still different apps with different needs, architectures and formats. They just synchronize most of their content between each other.

      they just synchronize

      But to be able to sync with each other, they still have to agree upon a standard, right?

        Yea, but that’s just a lowest common denominator (e.g. it doesn’t include things like lemmy community sidebars), and also generally not appropriate for a client application. ActivityPub transmitts all events that are happening (posts, likes …) between servers, and they are supposed to index and aggregate things (e.g. sum up votes, sort posts). It’s just not feasible to expect the the same from a mobile app for example, you’d have to at least create another standard for that.

        So services end up implementing their own client APIs to fit their needs. And imo that’s actually a good thing, because it allows them to try out features and specialize on different use cases. But afaik the ActivityPub people are working on another standard for client APIs, at least it’s on their radar.

    ActivityPub has a C2S (client to server) API in addition to the S2S (server to server) API, it’s just that nobody cared about it to implement it. And because nobody implemented it nobody iterated upon it so now it sits as this underspecified (and unusable) state.

    A unified API and a single login, are two separate things.

    A single federated authentication could be a good idea. But the various federated services are different enough that they should have different APIs.
