Question requiring PPK secure key, disabling user/passwd login

Hi - I am using Red Hat and was wondering how to disable username and password only login and require that a PPK secure key file be used for authentication ? I can log in using the secure private key and the public key that is in ~/.ssh/authorized_keys but i can still log in using the plain username and password login.

If you put an an exclamation point in front of the encrypted password it locks the password. I think at that point ssh still works but havent' tested it.

In sshd_config, enable PubkeyAuthentication, and explicitly disable all other Authentication methods.
