The main missing feature is password under duress that would open a different “user”. So even if you’re forced to give away your password they won’t get to the real account (some hidden profile or similar).
At least hidden profiles would be good enough for basic protection.
They have this which wipes your device, but you can get killed under duress. https://discuss.grapheneos.org/d/14722-using-duress-password...
