For an organization, a better strategy is to never store anything of value on the phone, and have a remote server in a safe place. The phone acts as a thin client to access server. The key in turn is easy to hide in a plausibly-deniable way or simply memorized. The server can also revoke the key, rendering it useless even if it is revealed at a later date. This is famously used by Uber to protect their systems from the French police, for instance. https://en.wikipedia.org/wiki/Uber_Files#Kill_switch https://en.wikipedia.org/wiki/Uber_Files#Kill_switch
