i attempted to change the admin password from the default of user: cisco, pass: cisco by using the following command from the terminal command line: hostname(config)# enable password (new password) encrypted
By adding the word 'encrypted', you told the ASA that the password you entered was the encrypted version of the password and not the cleartext version. If you had left off the word 'encrypted', the ASA would have taken your cleartext password and encrypted it in the configuration. A 'show run' would have shown the encrypted version of the password you entered.
You'll likely need to do a password recovery on the device. Instructions (though a little dated) can be found here:
Thank you John, but I can't do a password recovery because it has been disabled. So I won't be able to log into the cisco device with the password I updated and there is no way to login because I encrypted it?
That's correct. Since you've disabled password recovery, when you enter rommon you will be prompted to flash the device which will effectively remove the entire config. Do you have a recent backup of the configuration that was taken prior to the password change? If so, your only option at this point may be to flash the device and reload the backup config (with known good password).
Bummer. That's what I was trying to avoid. So what is the correct command to change the default admin password from cisco cisco?
