evaluate & add dezentralized authentication methods

[elmariachi111]

auth0 is beyond awesome but currently only supports federated and SSO logins. We'd like to avoid tracking our users as much as possible but we certainly need a "login" to identify e.g. content owners or users with certain rights or enable chats, you name it.

These are really good:

and watch out for e.g. Polkadot / Cosmos to launch a DID based, chain independent SSI soon ;)
