Hi,

Im not clear of your question, do you need to get back in to PIX , you do not know the passwords? or is it simply to change/reset the current passwords?

if to change passwords, bellow is the process to change password for telnet password and enable passwords, there is no default passwords in already configured firewall. PLS indicate if this is not the case.

seting password for telnet access

pix(config)#passwd

Seting password for enable mode

http://www.cisco.com/en/US/docs/security/pix/pix63/command/reference/df.html#wp1028841

pix(config)#enable password

after reseting these passwords before you logout and prior saving config telnet back into PIX from another system to test new passwords if all ok then you can save changes pix#write mem

These syntax commands applies to all fws regardless of code .

Also reseting passwords does not interact with PIX licensing information, nor reseting to factory defaults, but as good practice is always good to save the output of show version which will have PIX licensing KEYs.
