Resetting cisco Router ‘enable secret’ Password

Most tech guys and ladies have made this mistake of forgetting to reset the enable secret password during the initial configuration of a cisco router. After the cisco router finishes the boot process and arrives at the logon for the first time, the default username and password is cisco respectively. After you log on, the first thing you do is to enable the secret password by entering:

  1. enable – (this is entered at the Router> prompt)
  2. type config t at the Router# prompt
  3. type enable secret <password> in order to change the enable secret password. For example:  Router (config)# enable secret sylvudo
  4. then other configs follows…..

However, most folks forget to do this initial password reset/enable. And the consequences are that when you save your configs and reboot the router, you will no longer have access to privileged EXEC and configuration modes. So, to reset the password, follow the steps below:

  1. Power off the router, then power on again
  2. Hold down ctrl + Pause buttons (repeatedly) as the router boots up
  3. The router boots up to rommon 1> prompt
  4. type confreg 0x2142 at the rommon 1> prompt. (this bypasses the startup configuration where the passwords are stored
  5. type reset at the rommon 2> prompt. (the router reboots but ignores the saved configuration.
  6. type no after each setup question, or press ctrl+c in order to skip the initial setup procedure
  7. type enable at the Router> prompt
  8. type copy start run in order to copy the previous configs into memory
  9. issue the sh run command to show the config of the router
  10. type config t
  11. type enable secret <password> in order to change the enable secret password. – hostname(config)#enable secret sylvudo
  12. issue the no shut command on every interface that you use. If you issue a show ip interface brief command, every interface that you want to use should display up up
  13. type config-register 0x2102 or (the configuration register setting of your own router if its different from 0x2102. To find out your router’s config register setting, on the Router> prompt enter show version command, then scroll to the end of the lines.)
  14. press ctrl+z or end to leave the configuration mode
  15. type copy run start or write memory
