@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.
