Okay I'm IRGC, and I think this guy has some information. So I threaten him. He gives me his PIN. I get into his device, and can't find the information.

Did he wipe his device? Or did I get the wrong guy? I'm convinced he had the information, so whether he used the duress PIN or not I'm going to go through with the torture...

Also, even if you're right, then that would mean that the duress PIN is useful in places that aren't Iran right? Like the US? Canada?

Is the wiping functionality implemented so inconspicuously that you can't tell the device has been wiped?

  • Well, it doesn't sound like it haha... AFAICT it just wipes it, so I assume you'd get a blank OS when you logged in? Or maybe it wipes it and just doesn't log in.

    Actually I just watched this video and it sounds like it actually says "Wrong PIN" before deleting the OS entirely. There's a comment https://www.youtube.com/watch?v=41xbhw8N7NE&lc=UgzwdYjkLuGIb...

    Now I'm curious... the GrapheneOS guy has strong opinions strongly held so I'm surprised he'd agree to half-implement something.
