I cannot login with my second account because of the two factor authentication. It is an old account and I have not set up any. However, when I try to login I get promped to enter a Mobile Authenticator code, which I have not set up.
I do not receive an email for it.
And I can't go to the /security page because I get redirected back to /authentication, can't really do anything if I have not entered the mobile authentication code, which I can't because I don't really have mobile authentication set up.
