Saving my preferences

Hi
First of all thanks for the Great app, since the last Mediaplayer update the Languagemenu on my DVD Files are Working perfectly.
Is there a Way to Save my preferences and settings and saved shares
From the ATV.
I’m on Holiday the Next few Weeks and my dad wants to Lend my ATV for Testing
and i don’t want to let ihm use my Accounts and shares.

Greets
