Every attempt at using passkeys has been a step into murkier, less easily understood, less convenient security.
Passkeys may be a "step up" from password + TFA in terms of usability, but there's such a variety of implementations and explanations of how those implementations "keep me secure" - I feel like any idiot who grabs my phone when I'm not looking and can follow my unlock finger smudges on the screen can use my pass keys... No thanks.
