title: SetUP Oracle SQL Developer Credentials my new Windows installation
body: <p>I have downloaded Oracle SQL Developer version 20.4.1.407 from the Oracle site and installed in my Windows 10 machine after extracting it, and created a desktop shortcut.</p>
  <p>As i am beginner in sql, i dont have any new database to connect.</p>
  <p>Then I launched the SQL Developer application, and clicked on the + button to create a new database connection. In that window I put in:</p>
  <pre><code>username: scott
  password: tiger
  </code></pre>
  <p>But above credentials get:</p>
  <blockquote>
  <p>Test Failed: ORA-01017: invalid username/password; logon denied.</p>
  </blockquote>
  <p>It has not asked anything while installing SQL Developer.</p>
