If you enable 2FA for your passport account you won't get the trophy, you must enable 2FA for your forums account not your passport account.
so you must enable the 2FA for your forums account from this link: https://www.cubecraft.net/account/two-step
Ooo, that's very confusing, since I always get redirected to passport when I go to 'Password and Security'
Gonna try that one (when I find my password for the forums, because it's different from the Passport one?). Thanks a lot! :D
They didn't ask me to put the password when I enabled the 2FA, you just need an authenticator app such as: Authy desktop
