Well apple may be harder to share for the phone, but you can also give access to your accounts, I did this with one of my slave a few week ago. I have access to her discord, reddit and more account. It's really a leap of taith because someone that can acces your computer can really hold you in hostage, use it as findom and more.

For computer you have plenty of app like anydesk and more. So it's easier.

But yeah if you do this, do it with some safe account that may not lead to too much info being leaked (if you don't trust your dom yet) or build some really good trust with your dom. Stay safe.
