One key issue worries me. Could there be a two-key standard (one hot and one cold)? With such approach, if your hot key is hacked (since it’s stored within apps), you could use the cold key (stored in a secure hardware device) to generate a new hot key and somehow invalidate all the posts or actions made since the moment the hacking occurred.
