@arteteco OAUTH already makes that possible. Just need the activity pub services to start supporting it (some do, not many)
Ohh... marvellous. And how is the integration with the fediverse going?
@arteteco The only OAuth capable software in the fediverse that I know of is nextcloud with a plugin. But it isnt an OAuth provider, just a consumer. So in practice it just lets you sign on with your google or facebook account.
