Recovering a Lost Password
Recovering a Lost Password
To recover a lost enable or lost enable-secret password:
1. Change the Configuration Register
2. Reset the Router
3. Reset the Password and Save Your Changes (for lost enable secret passwords only)
4. Reset the Configuration Register Value
Note Recovering a lost password is only possible when you are connected to the router through the console
port. These procedures cannot be performed through a Telnet session.
Tip See the “Hot Tips” section on Cisco.com for additional information on replacing enable secret
passwords.
Change the Configuration Register
To change a configuration register, follow these steps:
Step 1 Connect an ASCII terminal or a PC running a terminal emulation program to the CONSOLE port on the
rear panel of the router.
Step 2 Configure the terminal to operate at 9600 baud, 8 data bits, no parity, and 1 stop bit.
Step 3 At the privileged EXEC prompt (router_name #), enter the show version command to display the
existing configuration register value (shown in bold at the bottom of this output example):
