My brother is stranded in nepal earthquake, need to bypass apple id to track location urgently!!

What is it is you intend to do by that requires you "bypass the apple id to track location"?

This is a user-to-user forum. We are powerless to bypass anything.

If it is possible to do this, you will have to call Apple support and see what they can do.

In the meantime, you should probably try contacting the Red Cross.

IF your brother wanted to be tracked he would have enabled Find My Friends.

But it's irrelevant anyway, because cell service is out in Nepal anyway.
