SSO for all Webdock websites

Currently, I need three accounts to be able to use all of Webdock's websites. I need one for the main page and this feedback portal. I need one for the support portal and one for the affiliates program. It would be nice to have just one account for all of these. But I understand that, for that to work, all systems would have to support some kind of OpenID or SAML protocol for IdP & SdP differentiation. And if you plan to support docs pull requests too but don't integrate with GitHub or GitLab for that, that would even need a fourth account.
