Comment on Why isn't using a key file the most common way to log into self-hosted servers?

  I think OP is talking about auth in services that you selfhost.

  For example elster.de forces you to sign in by entering a username and uploading a cert file.

  But mostbselfhosted services only have username/password logins.

    That sounds like aPasskey

      It does sound like one, but it isn’t.

      Passkey

      • Per-service key pair, unique per domain, Identity bound only to that specific account on that site
      • Challengeresponse via WebAuthn
      • Trust anchored only in the target service (no external CA)
      • Private key sealed in OS / secure hardware keystore

      Certificate login

      • Single global identity usable across many services
      • TLS client authentication with certificates
      • Trust established via certificate authorities and chain validation
      • Private key stored in exportable file or smartcard

    Yep which is why I use oauth2-proxy between these services and casdoor.

    If a service doesnt offer Oidc, just dont self host it. The SSO service can then be properly secured and even if its only a password, at least its not reused.

      Just put everything that doesn’t have OIDC behind forward auth. OIDC is overrated for selfhosting.

    That is certificate based
