Using Apple's Passkeys is just like using Apple's Password Manager. If you were using that you'd already be in that situation where your device unlocks all your passwords and all an attacker may need is your device passphrase. Passkeys from that perspective is no worse than existing iCloud passwords. You mention 1Password, and 1Password has just released their first steps into Passkey support and being a Passkey provider. You can download updated extensions for a number of browsers and use passkeys stored in 1Password, if you trust 1Password and like that flow of a secondary vault. The current rub is that you can't yet use passkeys from 1Password on iOS. That's hopefully a gap that Apple will fix soon enough in a similar fashion to how iOS supports multiple password providers.
