I have been using GrapheneOS for a couple of months now and have been really impressed with not just the extra features but the stability and the fact that it "just works".
One of the boomer parents is in need of a new phone and I plan to put them on GrapheneOS for the extra security and less bloatware. They are OK with technology in general. Semi-often need a "training session" but then they're all good. My general approach was going to be: GrapheneOS + Google Apps as needed (F-droid and other alternative stores will be too hard I think).
Question 1) I was wondering if others had done the same and what issues cropped up? Also any general feedback on settings and apps you found useful?
I also wanted to take the opportunity to get them using a password manager (Bitwarden). User has some issues with fine motor control and fine touch sense with their fingers, so typing in a long strong password will be difficult. So I was thinking of using fingerprint unlocking. Traditionally I have been a "hard no" on biometrics but the usability + upgrade from their current awful password security practices to Bitwarden + fingerprint to unlock vault will be a HUGE improvement (but I still just have some hang ups about biometrics in the back of my mind).
Question 2) Where exactly is the fingerprint template stored and how and where is the "finger print check" computation performed? Or can someone please point me to a solid resource on the technical details because almost everything I find on the Internet, at best, hand waves about a "secure element" and "locally stored" and that's it.
The phone used will be a Pixel 7 or possibly a Pixel 8.
Thank you and thanks to the GrapheneOS Team for your amazing work.
