Replacing or Recovering a Lost Password
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 configure terminal command to enter configuration mode:
Step 14
Hostname# configure terminal
Step 15
Change all three passwords using the following commands:
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.
You must configure all interfaces to be not administratively shut down as follows:
Step 16
Hostname(config)# interface gigabitethernet 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
Press Ctrl-Z (hold down the Control key while you press Z) or enter end to exit configuration mode and
Step 18
return to the EXEC command interpreter.
Caution
Do not execute the next step unless you have changed or replaced a password. If you skipped Step 13
through Step 16, skip to Step 20. Failure to observe this caution causes you to erase your router
configuration file.
Enter the copy running-config startup-config command to save the new configuration to NVRAM.
