Pass Fortnite Account Data?

Someone offered me an iconic skin in Fortnite when I push it. But to get the skin on my account, I have to give him the data and I'm afraid that he then adds harm to my account. What should I do?

Maybe come up with the idea that you will never get a skin if you do that, but then have no account?

My account has two factor authentication! Thus, the account remains in my hands. It's about what might possibly be done with my v-bucks, etc.

It depends on whether you know the person. Is it your friend, an acquaintance or just a stranger? If it is a friend or acquaintance and he is trusted, it's fine, unfortunately a stranger will most likely cheat you or strip your v-bucks.
