How to prevent factory reset.

[AC Question]

I've found that it is very easy for someone to just shut your phone off then boot it into recovery to factory reset it, and it doesn't ask for a password to factory reset. Meaning if someone steals your phone.. they can just factory reset it. Now my question is does anyone know of a way to prevent this?
I have a rooted LG G2. No custom roms.

No. But there are safeguards to put into place. Cerberus can survive a reset.
