Changing your cPanel username can have significant implications, and it is generally not recommended for security and stability reasons. cPanel does not let you directly change your own username.
The cPanel username is a fundamental identifier associated with your hosting account. It is used in various configurations and permissions throughout our hosting system, including database user and name prefixes.
To change names requires us to migrate your account to a new username while preserving your data and configurations. It's not a common or straightforward task, and it should only be done when absolutely necessary.
If you have a strong reason for needing to change your cPanel username, such as a security breach or a mistake during the initial setup, contact the support team (support@myhost.nz). We can probably help on a case-by-case basis. As with any other significant changes, it's a good idea to back up your data before making the request.
Please note the new username must be 8 characters (alphanumeric) or less.
