It's recommended that you change the password the first time you use the software, since the admin user that set you up in the system probably used a generic password. To change the password, click
Settings (from the main CMTS Admin menu), then
Change Password. The password screen will appear.

Just type in the current password.

and then press Tab or Enter. If you correctly enter the current password, you'll then be able to enter a new password (and also re-enter it to confirm it)

After entering the new password and then confirming the new password, click the Pencil icon (to save the changes).
NOTE: The password (and username) used to access the CMTS Admin program is the same used in the CMTS Logon program (discussed later in this documentation). The important point is that if you change your password here (in CMTS Admin), you'll use that new password to start up the CMTS Logon program as well.
