Zlatan so not sure about all of the options, but apparently graphene Os are working on a "duress mode" where you have a separate password that would wipe the phone.
So for example if you're arrested by the police and they force you to unlock the phone , you could type your duress password in "eraseme" or what ever you set, and then it wipes the phone. But apparently it does a more extensive and thorough wipe and also disables the phone from being turned off until the set up is complete.
Obviously I don't know when this will happen or how exactly it will
