Accessing 1Password with Passkey

The city I live in has had a lot of armed street robberies with groups of robbers targeting iPhones. They are getting more sophisticated. For example, they demand iPhone passcodes and quickly disable Find My iPhone. The keychain is easily read. That's why I don't use Keychain for any accounts. I use Screen Time to limit access to my Apple ID and iCloud account, but criminals will soon wise up to that.

Most consumers don't use separate password managers such as 1Password, so criminals probably focus on the keychain. I keep my 1Password app buried deep on my iPhone. There's a decent chance that robbers will not be aware of its presence during a robbery since there are practical time limitations before they jump back in their stolen cars and take off.

Risk of robbery is why I don't have any of my FIDO2 Yubikeys with me on the street. Since I don't use my keychain, I must use my master password to access the 1Password app on my phone. For phishing resistance, I want to use a passkey to access my 1Password account online.

For redundancy, I want multiple passkeys, which would be in 1Password and on my Yubikeys.
