title: How to to add permanently access to install private packages hosted by SATIS with access restriction in composer
body: <p>I would like to know how to add permanently credential to install private packages hosted by SATIS with access restriction through composer.</p>
  
  <p>Private packages are hosted by SATIS and have HTTP BASIC AUTH access restrictions. </p>
  
  <p>I ve added them in composer.json like this :</p>
  
  <pre><code>"require": {
    "vendor/privatepackage": "^1.0"
  },
  "repositories": [
   {
    "type": "composer",
    "url": "https://myprivatepackages.io"
   }
  ],
  </code></pre>
  
  <p>When i execute <code>php composer.phar install</code> i would like to not have to enter each time the needed credentials.</p>
