@FuzboleroXV I think that #NomadicIdentity is primarily about moving your identity _between_ accounts and corresponding hosts/providers. Being able to access several "nomadic identities" via one account is a byproduct for me, not so important. Main point here though is separation between a User (person or organization...), an Account and the "identity" (called an Actor in #ActivityPub).
@z428 As you may see from the discussion it the GitHub issue, the first and maybe the most undefined step in the #ActivityPub#C2S specification is authentication and whoami (account verification/discovery) steps. We agreed on concrete steps and endpoints with pleroma.site developer, but the same probably won't work out of the box with other systems. Anyway, I'm open to collaboration and aim at creation of really unified API, compliant with ActivityPub C2S.
@tom79 Yes, you can use Basic authentication with #GNUSocial (username + password). Several years ago I tried to find any working example of OAuth with GNU Social and didn't find any. Since that time #AndStatus supports Basic Authentication only with GNU Social.
