npm notice Access token expired or revoked. Please try logging in again.

I am trying npm install @capacitor/file-picker in an angulat/ionic project and always receive that message, I have created an account and login by executing npm login but when I try to install again, I got the same message, the two main questions here are:

Why should I need to create an account and login to install packages into my projects?
How can I succesfuly install packages now?
