So an earlier post got me musing idly on the topic of integration between multiple federated services. Wouldn't it be nice to be able to integrate video hosting, discussions, microblogs, image sharing, and so on in beautiful seamless glory! Post a pic in Lemmy, it's automatically added to your Pixelfed album; upload a song to your NextCloud and people can see it in your funkwhale profile. That kind of thing.

One of the things that I figure will be useful reach that goal, I figure, is a form of federated identity management. Linking accounts can be done, but there would be a lot of advantages to having one account that knows where the different services you subscribe to are located, allowing the integration to happen seamlessly in the background.

And looking around, I see that it already exists as a concept, but I can't seem to find anyone discussing or implementing it in the Fediverse. For something that would solve a lot of problems, including decentralized (and self-controlled) identification, SSO, and account migration, it seems like something that everyone would be jumping on.

Am I missing something?

It can be done with cryptographic signatures, like MetaMask login. But currently only crypto universe is doing that.

That way you wouldn't store login details on any server and the posts could be signed with your key, so editing them by instance admin would be practically impossible.

I think there already is such a social media website, but it's probably less popular than Mastodon/Lemmy.

I guess it is probably hard to expect users to be able to maintain their own keys. Idk, maybe there can be external identity services that helps users to store their keys, but mature users can just maintain their keys on their own? To avoid single point of failure, the key can be split into multiple parts so single compromised authority will not lead to account compromise... idk, just daydreaming.
