title: How to store login information for an api which requires Username - Password for the next session
body: <p>I'm working with an unofficial n26 API (<a href="https://github.com/PierrickP/n26/tree/develop" rel="nofollow noreferrer">https://github.com/PierrickP/n26/tree/develop</a>). The api requires the email and password to login to the account. 
  I don't want the user to login every single time so I need to store these information somehow.
  I can't find any way to get a session token or something for later use from the api. (maybe someone of you can find it??)</p>
  
  <p>So my question: How do I store Email/Password for later use in a secure way?</p>
  
  <pre><code>const N26 = require('n26');
  
  // Log into the account
  const account = new N26('example@mail.com', 'password');
  // Get the last 10 transactions
  account.then(account =&gt; account.transactions({limit: 10}))
  .then(transactions =&gt; {
      // Do something with it
  });
  </code></pre>
