No. I use a very long random password that is on a flash drive. I don't trust passkeys yet on a device that holds the path to my passkey/password file. Other sites, yes. In fact I use them on all that I can find that support passkeys and ragging my bank and financial service to hurry up and get them working. But I have had enough problems with them to worry about not being able to get to my passkeys/passwords because my Apple passkey isn't working for whatever reason.Thanks!
You're not using a passkey on your Apple account are you? That seems like the most significant place where you should be using one?
This will change but right now we are still in the stagecoach era of passkeys. (Actually, with some sites it seems that we are still in the era where Uug, the caveman, is chipping out the first stone wheel.) Too many times I log into some site (not apple) with a passkey just fine, then need to do something inside that needs security confirmation, and it asks for a password. (Looking at you, Amazon.) Or, "Passkey invalid. Reset password?" Now that is great security.
So. Not yet.
