I tried a few of the other .se domains listed. "andersnoren.se" appears to be for a single person, with no logins, but not marked so on your site. He seems to be a WordPress developer. And "com.se" seems to be a domain extension, like "co.uk" (https://www.ascio.com/blog/sweden-gets-a-new-domain-extension-com-se/ https://www.ascio.com/blog/sweden-gets-a-new-domain-extensio...), except unlike the UK I can't seem to find any examples of a "*.com.se" site. In any case, the concept of a passkey doesn't seem appropriate for "com.se".
