Fortnite 2factor authentication problems?

I made the 2factor authentication a few months ago and did not notice this code now I wanted to sign in on another new device and then the code is required what should I do now

You get a new code every time. You do not have to remember anything. Every time Fortnite wants a code, one will be sent to you!

Oke but who I sign on my phone, we also want a code but where can I get that

Normally you will receive an e-mail.
