Fortnite: switch account data?

I wanted to know if I can also play on my PC with my Fortnite account from the Switch, but I can't find the login data and when I try to log in to the Epic Games Launcher with Switch I only create a new account: /.

Yes you can, I did it too. I just logged in via google doesn't know what it looks like to you but where i logged in with google i came in immediately hope i could help you

So the account data from the switch account on which the acc is?

I revised again simply with the google data as on switch or just enter your epic name and password hold
