Latest release of #GrapheneOS finally shipped the long awaited duress PIN/password implementation. If you have a spare device, we recommend trying it out.

We've added initial documentation to the features page:

It near instantly wipes and shuts down.

We've also finally added documentation on our USB-C port control to our features page:

https://grapheneos.org/features#usb-c-port-control

Most users can set this to "Charging-only when locked" without a loss of functionality or even "Charging-only" if you don't use USB accessories, DisplayPort or MTP.

Default is "Charging-only when locked, except before first unlock" to avoid locking users out of devices with a broken touchscreen. The main threat model for this is defending the device until the auto-reboot timer started when the screen is locked gets user data back at rest.
