Help me at fortnite?

I wanted to know how I can find out where to see which e-mail to play Fortnite with. I have problems with the 2fa activation. According to Epicgames I activated it but I still didn't get this dance. Then I thought maybe I was registered with another email…

If you ever bought something, you should find the receipt in the correct mailbox.

Eg v bucks or what

To play Fornite you have to have an account with Epic Games, which contains the email you use.

Yes
