Will GrapheneOS be able to fully support passkeys? https://developers.google.com/identity/fido/
This is the part that makes me wonder:
"What happens if a user loses their device?
Passkeys created on Android are backed up and synced with Android devices that are signed in to the same Google Account, in the same way as passwords are backed up to the password manager.
That means a users' passkeys go with them when they replace their devices. To sign into apps on a new phone, all users need to do is unlock their phone."
Is it possible to provide this using Sandboxed Google Play Services? Or will this probably require more privileged access that GrapheneOS can not support?
