title: Npm unable to authenticate, your authentication token seems to be invalid
body: <p>I am trying to do npm install on a GitHub project that I have pulled. After a while, it gives me this npm login error.</p>
  <p><a href="https://i.stack.imgur.com/arB6s.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/arB6s.png" alt="enter image description here" /></a></p>
  <p>After the error, I have run npm login and successfully login with my credentials but it keeps giving me the same error.</p>
  <p>I have also uninstalled node and npm and installed them again, updated them to the latest versions, deleted information inside the .npmrc file and nothing seems to work.</p>
  <p>I have tried to do npm install with other GitHub projects and it is working fine. I have no idea why this is happening</p>
  <p>Thanks for the help</p>
