Finding someone else's iPhone with Find My Phone

[drsox]

My partner and I have the same iPhone, same version of iOS with Find My Phone enabled.
If one of us loses/has the iPhone stolen can the other access it and manage it through the other iPhone or Mac ?

I can manage my "lost iPhone" with my Mac - she can do the same with her Mac to her iPhone. BUT, if we are both away from our home base when something happens - then what ? If I can't access her Mac (e.g. I don't know her admin password or iCloud login) - then what ? How do I get her iPhone on my list of findable devices ?

What am I missing here ?

Thanks

Yes you can. A friend of mine lost his iPhone and we tracked it from mine.

Brilliant, thanks. The answer lies in using Family Sharing. Never needed to do that before.
