I want to have the same username on Github, Twitter and NPM. I've updated my Github but my NPM one's still the old one. Can this be done? I'm not concerned about breaking the URLs for my packages because nobody's using them except me.
Well, you can't just change the name, but you can create a new one, and switch over to using that instead.
npm owner add <pkg> <newusername>
npm owner rm <pkg> <oldusername>
A few notes:
Adding the keyword "rename" so this shows up in search better.
The syntax is actually <username> <pkg>, not <pkg> <username>.
It'll be worthwhile updating your profile on the website, e.g. as I have done.
