I've heard that duress pins/passwords and false roots and the like aren't actually helpful. IIRC the argument was that if they're familiar with your OS they're familiar with the duress pin capabilities.
But even if that's the case, there's no way to tell if a duress pin was used, right? And if you're in a place with weak legal processes and they decide possibility=guilty, then the duress pin doesn't make things worse, right? I.e. if they wanted to do something to you, then "lack of evidence due to duress pin" is no different than just "lack of evidence" i.e. the pin at least doesn't make things worse...
Simple, "if you try to enter the duress pin, you and your family and your friends, will be beaten to death, and I will make you watch them die one by one, unless you tell me the real pin, and then kill you next"
Increasing the extreme and cruelty of violence. It always works. That also means the "investment" of each action will have higher stake, though.
It is not an intimidating thought experiment, it is being used in the 2026 Iranian Protest by the IRGC
Even in that scenario, having the duress pin option does not make things worse. It's functionally equivalent to smashing the phone, just easier to do with one hand.
i.e. whatever they do to you if you wiped the phone via duress PIN, they would already do to you if you managed to smash the phone.
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?
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.

Now I'm curious... the GrapheneOS guy has strong opinions strongly held so I'm surprised he'd agree to half-implement something.
The main critique I’ve seen of the duress pin is that it causes undue trouble. The obvious counter argument is that if you genuinely have the need for a duress pin, it’s worth its weight in gold. If the severity of the charge or physical punishment (in countries without due process) would in any way be less by NOT having xyz data on your phone, then it’s helped. Say, the difference between 10 years for destruction of evidence and 80 years for espionage.
For sure, but these LARP situations are mostly based on defending against a highly motivated and powerful entity like the government.
But other situations like against thievery, domestic abuse, or brute force deterrent (ie: setting a simple duress code that is likely to be triggered, say 1111), it has the potential to work well.
Graphene brings out some of the best of android. Profiles are first class citizens, private spaces within the owner profile (I think all profiles can have them now?), and app pinning are great.

Duress PIN is a feature started by security systems. Entering the dress code would seam as if the security system was disabled while in the background it would contact the security company to send in the police.

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...

These kinds of threats should, really, only strengthen our resolve. After all, they clearly demonstrate the opposition's danger should they succeed.
It’s just an optional feature that could be used in a much less extreme situation.
It could be used in a situation where that infinite escalation of violence isn’t likely to happen.
E.g., a petty thief who says “gimme your pin”
Once they have the phone unlocked they don’t care that it’s wiped.

It also doesn’t have to be used against a government.

For people that don't know.
Duress PIN is a feature started by security systems. Entering the dress code would seam as if the security system was disabled while in the background it would contact the security company to send in the police.
Maybe generally, but in this case it seems like it just wipes the device.
I wonder if being able to block access to/hide specific apps, e.g. banking apps or whatever could be a good idea here?
