What are EXEC and ENABLE passwords for and why should I set them?
The EXEC and ENABLE passwords provide two levels of security to your Cisco 675 or 678 modem. The EXEC password controls access to the Cisco 675 or 678 modem, and the ENABLE password controls whether changes can be made to the CBOS (Cisco Broadband Operating System). Setting these passwords will prevent unauthorized access to your modem. Unauthorized access could potentially cause a reconfiguration of your modem without your knowledge (presuming your modem is set with telnet enabled). Using the PPP Conversion program (for Microsoft® Windows®) will give you a window in which you can set the EXEC and ENABLE passwords. If you need to set these manually, refer to How do I manually set my EXEC and ENABLE passwords.
