The nice thing about passkey is that unlike password, you can have multiple per account.
So you can register a passkey from 1password to website A, and also register a passkey from Apple keychain to website A, and also register a passkey from Google account to website A, and also register a passkey from yubikey to website A, so even if you are locked out from one of your accounts, you still have several other ways to log into your account at website A.
And _if_ your, say, Apple keychain is compromised, you can just revoke the passkeys from your Apple keychain from all the websites (yes it's tedious, but it's doable).
