I am sure it was discussed here before, but I can’t find a good way to search this community.

Are there any arguments against having a user’s identity federate, and be compatible across platforms?

For example, let us say I sign up with my instance, matcha_addict@lemy.lol

But what if I go on mastodon, and I want to have my own micro blog. Or maybe go to write freely and post some blog posts. I’d have to make a different account on each one.

What if mastodon or write freely could just let me log in with my lemmy account (or lets call it federated account). This has several benefits:

  • users don’t have to scratch their head on if I am the same person or not across these platforms
  • theoretically, someone following my feed can get updates on what I do on multiple platforms

Now I understand this would be difficult to implement and iron out all the edge cases, but am I missing anything on why it wouldn’t be a desirable feature, given it is implemented?

    We host instances for trans and gender diverse folk, to provide a space that explicitly puts their safety first.

    Take away the idea of an instance as a community/identity/distinct space, and the goal for these places existing is gone. Instead of a community and a safe space, we become a generic bit of hardware that enables transphobes as much as trans folk.

    That’s not something I’d be keen to keep sinking my own funds in to to support.

    What I’d much rather see is instance based accounts, however, with the ability to take over/migrate them from other instances, so that if an instance goes down, people can still keep their identity. It would also allow instances focused on protecting minority communities to keep doing that.

      This is a very valid concern and I should clarify a bit about the mechanism I have in mind.

      An instance admin can decide which instances it federates identities with, similar to how regular federation is done (but maybe these would have separate lists)

      So, in your case, you would only federate identity with instances you trust to have done proper vetting. It wouldn’t be by default that having a federated instance means you have access to login the entire fediverse.

        White listing encourages centralisation because it makes it really hard for new communities/instances to develop the trust they need to be included in existing white list circles.

          This white listing will not impact regular federation, so smaller communities will still get the same benefit they get now. They will only not get identity (for logins) federation until they gain trustworthiness

        What do you mean by “federates identities with”? I mean users are already federated, you can see my profile on your own instance. What is the mechanism you’re talking about?

      Maybe failover identities that consume the primary identity’s activities as a log. The failover identity (let’s call them jump clones for fun eh?) can be stood up as primary if the primary goes down (gets banned, instance dies, etc)

      the ability to take over/migrate them from other instances, so that if an instance goes down, people can still keep their identity

      I can definitely see user migration from one ActivityPub server to another being a possibility, but I really don’t see how that can happen if one of the servers is down. That’s too late then. If you could migrate a user from a server that is down, what prevents you from migrating a user from a server that is still up and doesn’t want to do the migration? You could just pretend that it is down and do the migration anyway? I have no idea how that would work.

        The proposal I saw was basically a way of “signing” your posts, and then when they federate somewhere else, you can create an account on another instance and “claim” the posts that have federated there as yours, with your private key.

        Obviously, you couldn’t access posts that never federated to the instance in the first place, but even with some lost content, it would let you edit, and post new content.

        And as I understood this proposal, basically, you could have multiple active accounts, all of which are “you”, and allow you to control your content with the same permissions.

          Yea that could in theory be possible - the big problem is that it requires people to hold their own private key and manage that, both securely and conveniently. And well… tbh I just don’t see that happening. If you need to keep your own private key and also keep your own password, I really don’t see any non-techie people ever using the fediverse.

          There’s also the issue that if that private key is leaked, there is no going back. Your identity is stolen and you can do nothing to take it back. This is different from if your password gets leaked - in that case, an admin could in principle step in and reset your password and you could regain control of your account. This happens all the time when people’s Facebook accounts get “hacked”. They report it to Facebook and get their account back. This is impossible if it relies on a user-held private key.

          It’s a neat technical solution that unfortunately forgets the human, as is often the case.
