Just a curiosity. Theoretically FRP (factory reset protection) can use the current login password as a way of authentication after reset. But it everything on the web states that you will need a Google account to take advantage of he feature.
No it doesn’t.
The thief would have to unlock the phone to factory reset, and therefore could change the login password before factory reseting, so local account wouldnt be sufficient would it? (I am making some assumptions, i could be wrong)
Doesn’t GOS have a recovery system with which you can wipe the data, just as on any off the shelf phone?
If I recall, their website FAQ has a big, technical section on this.
Indeed. Here is the section https://grapheneos.org/faq#anti-theft
But the short answer is: although it can be implemented to use a local authentication method, but that would easily cause bricking. Plus the limited thief deterrence potential it provides (given the limited user base of graphene, I assume) hence it is low priority.
