title: How to use multiple npm auth tokens
body: <p>I need to set up multiple npm tokens that are under two different scopes</p>
  <pre><code>@scope1:registry=https://registry.npmjs.org/
  @scope2:registry=https://registry.npmjs.org/
  //registry.npmjs.org/:_authToken=${NPM_TOKEN}
  </code></pre>
  <p>I have tried to add the an auth Token to each scope</p>
  <pre><code>@scope1:registry=https://registry.npmjs.org/:_authToken=${TOKEN_1}
  @scope2:registry=https://registry.npmjs.org/:_authToken=${TOKEN_2}
  </code></pre>
  <p>But I am getting a <code>405</code> when I am trying to install a package.</p>
  <p>I tried looking up the docs: <a href="https://docs.npmjs.com/using-npm/config" rel="noreferrer">https://docs.npmjs.com/using-npm/config</a> but I cannot find a way to specify different tokens for different scopes</p>
