Account linking question

I am trying to link my account to Facebook.
However, I want to link it with Naver mail, not Gmail.
Facebook’s mail is made of Gmail. Is there any way to change it to Naver mail?

I have a Facebook made in Naver Mail !!
but I don’t know how to change my Facebook account

Just link it to your facebook mail. I use yahoo and its okay. As long as it is linked your facebook profile, i think all mail work
