Just like apps and websites implement “Sign in with Apple” and Google couldn’t we build some kind of federated authentication provider? Then everyone creates an account there and fedi apps can implement an easy way to authenticate users. Even non fedi apps could use it. I imagine user interaction between different fediverse platforms would be much easier too.
I guess could run an auth instance. Ideally everyone would run their own, keeping your data safe.
Is there something likes this already? Saw some discussion here but not much else https://socialhub.activitypub.rocks/t/single-sign-on-for-fediverse/712
I think I understand the self hosted identity server part, and authenticating with it on different sites. But what is the federated element you’re talking about? What would that instance federate, and with whom?
If we’re moving into a single sign-on for several federated accounts, that’s cool. People have been asking for that for ages! But the identity provider itself wouldn’t (need to) be federated for that to work, right?
I’m guessing it would have to federate with whatever platform decides to implement the single sign on feature. Not sure will leave the details to smarter people haha. Hope some day it could be implemented because it would be pretty useful if it can be done in a secure way.
FWIW, you can setup IndieAuth — on its own or as part of the IndieWeb plugin suite for Wordpress. It may not be quite what you’re looking for, but it’s a step in the right direction?
