Any idea of using this broken iPhone 6 plus?

I brought this iPhone to Apple Store, and they said they can't fix it, so replacement with $326 only. (Not sure exchange with new or refurbished one)

I can sell this like this for parts, but there may be my passwords those things still there, and I can't access to delete them anymore.

I'm wondering what I should do with this. Any ideas are appreciated!

Depends on may be able to fix it yourself spending what's wrong with it
