NPM incorrect or missing password

I was working on a project, and everything was fine. I do not know how this happened, but when I went to npm install another package I got an error of “Incorrect or missing Password. If you were trying to login, change your password…” Which this has nothing to do with a password. I did some research and all over it mentions delete the package-lock.json. This project does not have that file in it, so I am wondering where to delete it from?

What is the package that gives the error? Can you install other packages?
