Recovering from a Lockout
In some circumstances, when you turn on command authorization or CLI authentication, you can be
locked out of the ASA CLI. You can usually recover access by restarting the ASA. However, if you
already saved your configuration, you might be locked out. Table 1-2 lists the common lockout
conditions and how you might recover from them.
