I use a saved passkey in Bitwarden to log into a PWA. I use the PWA's 'login with biometrics' option, and I have no fingerprint setup on my device (doesn't work with the privacy screen I use on my Pixel). So instead of using the fingerprint, my phone prompts for the unlock PIN.
This works perfectly, however I'm curious as to why the PIN isn't scrambled, as currently set on GOS (i.e. it's scrambled for boot and unlock).
Is this a missing feature from GOS, in that the PIN number keyboard is within the OS's API for third party passkeys management, or is this a Bitwarden issue?
