Destroy old Apple IDs from my iPhone
You cannot 'destroy' Apple IDs, they last forever.  
You only need one ID. You can change the associated email address if needed.  
The ID used to set up the phone or to download any software is the only one that can ever update or restore it.  
Giving someone else your ID &amp; password details is a security nightmare &amp; foolish in the extreme - open to abuse at any time in the future.
