If you are like me you can't stand the default authentication on all Cisco devices.  I hate giving out one password that allows people to telnet into the box and another for enable mode.  I like creating usernames and having people log in with their own password, that way I can remove access without needing to change all my passwords.  Here are a few commands I commonly use on ASA Firewalls to setup AAA authentication:<!--more-->

aaa authentication enable console LOCAL

aaa authentication telnet console LOCAL

username &lt;USERNAME&gt; password &lt;PASSWORD&gt; privledge &lt;LEVEL#&gt;
