I'm curious how 1Password can say passkeys cannot be stolen, and yet passkeys are sharable within 1Password. Wouldn't an attacker stealing my 1Password credentials (secret-key/user/pass) also get (cf. steal) my passkeys stored in 1Password?

Regardless, I'm excited for passkeys: passwords are already abstracted out with password managers, and now they're going a step further of not being revealable w/ passkeys. However losing the escape hatch of reading a password off my phone into an untrusted computer is quite the use-case loss.
