Can you do it without if so how? I can't because I don't have the email.
Can't.
Why should that be otherwise possible when Epic says that this is only possible with 2FA?
I'm desperately ok? What should I do.
Nothing.
If you don't have the mail, you can't do anything.
So?
You can also activate 2FA via SMS.
The mail doesn't have to be confirmed if you haven't.
