Our upcoming 2-factor fingerprint unlock will make using a strong passphrase as primary unlock method practical via fingerprint+PIN secondary unlock instead of fingerprint-only. Great for people who want to avoid relying on secure element throttling but don't want fp-only unlock.

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:

https://grapheneos.org/features#duress

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.

Our upcoming 2-factor fingerprint unlock will make using a strong passphrase as primary unlock method practical via fingerprint+PIN secondary unlock instead of fingerprint-only. Great for people who want to avoid relying on secure element throttling but don’t want fp-only unlock.

    Use the duress pin feature along with Phone Lock app, which disables biometric login for next unlock on sudden gyro movement shock. Thus, enteing into pin/password only mode, where duress feature can be used easily.

      Last time I checked, that app uses accessibility services, which are not recommended by the GOS project. As accessibility services greatly increases attack surface if any app using these services are compromised.
