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
@tomatol If Nomadic identities get implemented then yes, I’ve heard there were somepeople working towards it but haven’t heard much since.
Still, not sure I’d be to comfortable using a Fediverse server (especially one not hosted by me) for my identity. I’ve already lost an account to a SQL database dying, and some swaths of the fediverae are rather quick to ban or defederate.
Nostr and AT do it pretty well, though, using a key pair you control to sign into other services using your account. If something were attempted on the Fediverse this would probably be the best way to go about it.
