How can I bypass the PSN authentication?

I want to link my friend's Fortnite account to mine so I have his skins on my account. But I have to confirm the email address of my friend (who played Fortnite on the PlayStation). A message will be sent to his email but it has not arrived yet. I wanted to ask how to avoid this authentication. (Incidentally, I play on the PC if that matters)

Unfortunately you can't link them, you can only play on one of them, they can't be put together. Sorry otherwise almost everyone would have all skins XD

Had I also thought xD Thanks anyway
