title: How do I extend Adminer to support SQLite databases with login?
body: <p>I am running a server which hosts both a MySQL instance (with several databases) and some SQLite files. I would like to use <a href="https://www.adminer.org/" rel="noreferrer">Adminer</a> to manage all of them, provided that valid credentials are given by the users. Also, a list of databases should be populated.</p>
  
  <p>In case of MySQL, valid database users can be used and the connection works out of the box. However, SQLite support must be added explicitly. Adminer gives this error:</p>
  
  <pre><code>Implement login() method to use SQLite.
