"Login with password key" Removing the Button

I only want to use the google login, how can I remove this option?

You can hide it with some CSS in a theme component, something like this should work:

.passkey-login-button {
  display: none;
}

That only hides the button, it still allows users to create and login with passkeys via autocomplete in the main login form (on the left of your screenshot).

Thank you very much, it worked.
