Explanation:
Enable vty, console, AUX passwords are configured on the Cisco device. Use the show run
command to show most passwords in clear text. If the service password-encryption is used, all the
passwords are encrypted. As a result, the security of device access is improved.
pay close attention to the word encrypted. the term is somewhat hazy. If you are unfamiliar there are different levels of hashing/encryption in cisco devices. One of which is very easily reversed but is a true encryption method. Contrary to that, there are two levels that are actually not a reversible form (making them technically a hash, not an encryption), which makes them much more difficult to circumvent.
