Replacing or Recovering a Lost Password
Router# show startup-config
Scan the configuration file display looking for the passwords (the enable passwords are usually near the
Step 12
beginning of the file, and the console login or user EXEC password is near the end). The passwords
displayed look something like this:
enable secret 5 $1$ORPP$s9syZt4uKn3SnpuLDrhuei
enable password 23skiddoo
.
.
line con 0
password onramp
The enable secret password is encrypted and cannot be recovered; it must be replaced. The enable and
console login passwords may be encrypted or clear text. Proceed to the next step to replace an enable
secret, console login, or enable password. If there is no enable secret password, note the enable and
console login passwords, if they are not encrypted, and proceed to
Do not execute the next step unless you have determined you must change or replace the enable, enable
Caution
secret, or console login passwords. Failure to follow the steps as shown might cause you to erase your
router configuration
Enter the configure memory command to load the startup configuration file into running memory. This
Step 13
action allows you to modify or replace passwords in the configuration.
Router# configure memory
Enter the privileged EXEC command configure terminal to enter configuration mode:
Step 14
Hostname# configure terminal
Change all three passwords using the following commands:
Step 15
Hostname(config)# enable secret newpassword1
Hostname(config)# enable password newpassword2
Hostname(config)# line con 0
Hostname(config-line)# password newpassword3
Change only the passwords necessary for your configuration. You can remove individual passwords by
using the no form of the above commands. For example, entering the no enable secret command
removes the enable secret password.
Step 16 You must configure all interfaces to be not administratively shut down as follows:
Hostname(config)# interface fastethernet 0/0
Hostname(config-int)# no shutdown
Enter the equivalent commands for all interfaces that were originally configured. If you omit this step,
all interfaces are administratively shut down and unavailable when the router is restarted.
Step 17 Use the config-register command to set the configuration register to the original value noted in Step 3
or Step 8, or to the factory default value 0x2102 as follows:
Hostname(config)# config-register 0x2102
Step 18 Press Ctrl-Z (hold down the Control key while you press Z) or enter end to exit configuration mode
and return to the EXEC command interpreter.
