Ability to rename / delete primary administrator account

Dudley_Winchester

I'd love to be able to create my own primary admin account username with something different to "admin"
At present, a hacker only has to be able to guess a password, as the username "admin" cannot be removed or disabled. I'd prefer to make unauthorised access harder, by forcing would-be hackers to also having to guess my USG/ATP username.

Or just make the admin password really long and make another admin account
