I asked a question on christianity.SE, which I don't want to be associated with my account "Jan Turoň", so I didn't login to that page, just submitted a question as a new user "humanist" with the same e-mail and password as "Jan Turoň".
My question was migrated to hermeneutics.SE, where I have no account, yet I'd like to accept the answer. Where is the "humanist" account created? I tried to login with Stack Exchange, but no success.
Do I need to create another Open ID, link it with "humanist" and login with that Open ID, or is there an easier way?
