How can I retrieve a user name and password?
Drupal does not store passwords, but rather password hashes. There is no way to recover the password. You can use Drush to either set a new password or generate a one-time log-in link:


Reset PW: drush upwd &lt;username&gt; --password="&lt;password&gt;"
One-time login-in link: drush uli &lt;username&gt;
