I have been using GOS on my pixel 7 for quite a while and recently noticed that it is able to automatically connect to my home wifi after a full reboot, even before any users (including the owner) is unlocked.
I am also able to ping the phone from another device in the same network so this isnt a ui bug.
Doesnt this require the known wifi networks and credentials to be stored unencrypted somewhere?
Having access to previously connected wifi networks could be used to tie a phone that was used wifi only, with random macs and without simcard to a specific location.
My previous understanding after reading https://grapheneos.org/faq#encryption was
that only identical to public copies of the Firmware and OS partitions are unencrypted and everything else is encrypted ether by the owner or another users key.
It would be great to have a section in the FAQ that list everything stored unencrypted.
Is there any other information besides identical firmware / os copies and wifi credentials stored unencrypted?
On which partition are the wifi credentials stored?
Thanks
