GrapheneOS provides users with the ability to set a duress PIN/Password that will irreversibly wipe the device (along with any installed eSIMs) once entered anywhere where the device credentials are requested (on the lockscreen, along with any such prompt in the OS).

The wipe does not require a reboot and cannot be interrupted. It can be set up at Settings > Security > Duress Password in the owner profile. Both a duress PIN and password will need to be set to account for different profiles that may have different unlock methods.

Note that if the duress PIN/Password is the same as the actual unlock method, the actual unlock method always takes precedence, and therefore no wipe will occur.

Mhm i can imagine that GrapheneOS will be marked as an illegal OS once Interpol and others get wind of this kill switch.

[–] boldsuck@scribe.disroot.org 6 points 2 years ago

The people Interpool is after don't need Duress. They simply refuse to give out their password. Current Pixel and iPhones phones cannt be cracked with forensic tools. https://discuss.grapheneos.org/d/12848-claims-made-by-forensics-companies-their-capabilities-and-how-grapheneos-fares

Doubt it, wouldn't they just clone the flash first?

irreversibly wipe the device

And for anyone to actually go through the trouble of cloning a flash chip, you'd have to be an extremely high profile target.

Who the fuck do you think interpol are targeting? Lmao

That may be useful

[–] smileyhead@discuss.tchncs.de 21 points 2 years ago (1 children)

Wonder if this say a big "WIPING..." and shows a blank profile then.

Because it would be much more useful if this would erase real profile and then quickly switch to some fake profile looking real.

It doesn't say anything. It shuts the device down almost instantly, and simulnateously wipes the encryption keys from the secure element, ensuring that the data stored on the SSD can't be decrypted.

Why didn't you contribute this feature sooner then?

[–] ryannathans@aussie.zone 6 points 2 years ago (1 children)

I'm maxed out on open source contributions myself right now as maintainer of a large project

[–] MachineFab812@discuss.tchncs.de 2 points 2 years ago

... and I've been told I'm demanding and entitled, but here's some jackass who downvoted one(@ryannathans) who is doing the work. You or I can never do enough to be worthy to request certain features or bug-fixes be given higher priority.

These people need to go back to Spez's, Musk's, or Zuck's playground, since they love having no say so much.

Cool feature, I wonder if a duress fingerprint will be introduced in the future?

[–] Jolteon@lemmy.zip 30 points 2 years ago (1 children)

I feel like that would be a lot easier to accidentally trigger.

[–] yeehaw_cosmonaut@reddthat.com 4 points 2 years ago (1 children)

You're not wrong, but like the duress pin, it would be a nice feature to have. Not everyone would have to set a duress fingerprint, just the people who find value in it.

[–] refalo@programming.dev 7 points 2 years ago (3 children)

something something destruction of evidence

[–] autonomoususer@lemmy.world 19 points 2 years ago* (last edited 2 years ago)

What evidence?

[–] Jolteon@lemmy.zip 7 points 2 years ago* (last edited 2 years ago)

Alternately, it could unlock the phone while also erasing specific parts of it, like message history and call logs, potentially replacing them with something you'd set up previously.

Edit: and obviously it would disable the duress pin and set the unlocking pin to it.

[–] DetectiveSanity@lemmy.world 3 points 2 years ago

Depends on what you did! Say for example they're using Graphene to harass/paedophilia then they already have a copious amount of evidence on hand since they are there.

For organising peaceful protests that seems less of an issue and the other end of the chats is the weak link.
