Actually, it is still a problem, because passwords are a shared secret between you and the server, which means the server has that secret in some sort of form. With passkeys, the server never has the secret.
You can share passwords without the server seeing them. Many managers don't but there's nothing infeasible there. You just have a password to unlock the manager. Done.
What I'm getting at is that a web server has a password, in some form. And so if that site gets breached, your password itself may not get leaked, but the hash will. And if the hash is a common hash, then it can be easily cracked or guessed.
Ultimately I'm pro passkey but when it comes to password managers: if the hash of your vault is easy to crack you've fucked up big time. There shouldn't be any way to crack that key with current tech before the sun explodes because you should be using a high entropy passphrase.
Oh, you absolutely should. And if you are not, that is nobody's fault except your own.
