Threat models for storing passwords, TOTP and passkeys in a single password manager?

TheDoc: > I believe Apple now defaults to storing passkeys in their password manager to provide better portability but you might still have the option to store it on hardware instead. I just tested trying to save a passkey offline on my iPhone. It forces me to either (a) use another device (physical key or a device running iOS 16 or later), or (b) turn on iCloud Keychain. I would rather save it on a physical key than having it on the cloud and dealing with a cloud breaches. TheDoc: > YubiKey also works with NFC so I think it should support both an iPhone and PC. I didn’t know this. I will look into it.
