I’m will sell my gaming laptop, must I sign in again?

I am gonna sell my MSI gaming laptop. And I have factory reseted it already. And it tells me: “sign in to a microsoft account to proceed”. But since I’m gonna sell it, I don’t want to sign in again! Now could I sell it so when they get it they can just sign in with their microsoft account? Or do they get access to mine? Before I factory reseted it my microsoft account wasn’t on the laptop. I was only signed in as a local account with no password. So I don’t really see why it would appear on the laptop again. But just asking to be sure. For now I haven’t logged into any Microsoft account. I have just finished the factory reset. Thanks.
