Linksys WRT54GC lost/forgotten username password recovery

• WRT54GC is a compact 802.11g access point (AP)
• A new AP was bought to extend range, but the customer support center refused to give details of the username and password for activating the new AP.
• After a while, restarted the older WRT54GC with the working settings, logged into the web page and ran a backup "settings" option on the host machine. This saves a file on the host machine,as  a binary file.
• Ran a hexdump utility, like dd on unix with the ASCII option, and one can clearly see the username and password.
• Maybe this option will work on other routers too. Tried this on an WRT54G and all settings can be seen after using the hexdump utility.
