Currently I am using the same password for everything beside the WHM and Shell which assigned by Lunarpages. Other than that they all using the same password, wonder if that will create a security issue.
Also, how do I change the FTP Backup server password? I tried to change it on cpanel backup configuration, but I still able to log in with my old password.
The reason I want to update all my password is because I just switch a new web development company and trying to avoid the previous company to log in.
Is there a way the previous company could log in via some kind of ftp by using mySQL user name and password. Or as long as I changed my cpanel log in, there is no way for them to access to my database even though they are the one to create the user name and password for the mySQL. Please suggest

Thanks,
Francis Y.
