Could you elaborate please? What aspects are you referring to? Biometrics for pam? Facial recognition support? Genuinely curious, since I saw the bounty to streamline keepass and pam auth for instance, or howdy for biometrics. Looking forward to both but do you have more information?

Microsoft Defender for Endpoint works on Linux too.
But like... Why.

i was asking about the passkeys specifically tho, not the biometric auth part of it
linux only supports hardware security keys like yubikey, not on-device passkeys atm
