Unable to locate apple.com passkey on iPhone 11

Hello,

on my iPhone 11 iOS 26.1 I logged into the website apple.com using a passkey.

My question is where is the passkey?

I checked iPhone 11 iOS 26.1 -> tap Passwords app -> Passwords -> tap Passkeys -> no apple.com passkey there.

I checked a 3rd party password manager which has the Apple username and password, but has no passkey.
