The cPanel username serves no real function other than being used for logging in to the cPanel server. Beyond that, nobody else except for the VentraIP customer should see or know what the username is. Changing the username is only cosmetic and comes with a few risks. Before going ahead with this kind of change, please keep in mind that there may be some changes you need to make to your website and other files to ensure your website continues to function without any issues. They are:
Changing the username will break any MySQL connections currently being used in files referencing the previous username, and updating those files are my responsibility; and
Any files using absolute paths are the user’s responsibility to update.
You will be prompted to acknowledge these points when changing the account’s username.
