If you receive the message Invalid Root Password when trying to change your root password via our control panel, it’s likely for one or more of the below reasons:

• The password is not at least six characters long. Please ensure your password contains at least six characters.
• The password contains an unsupported special character. Passwords may only contain letters, numbers, dashes, and underscores. 

If you require special characters in your password, you will need to use the passwd command from an SSH/Shell session to set your password manually.
