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:
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
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.
