How to reset admin password

Thanks for the helpful hints ! I found a simple script provided by OSTraining meant for Drupal 7 and I try changing some api names to backdrop and it works for me. Let me know if there's any issue with this way of working or better codes to be done. Thanks !

Here the steps:

Step 1: Create a short PHP script with code below

<?php
define('BACKDROP_ROOT', getcwd());
require_once BACKDROP_ROOT . '/core/includes/bootstrap.inc';
backdrop_bootstrap(BACKDROP_BOOTSTRAP_FULL);
 require_once BACKDROP_ROOT . '/core/includes/password.inc';
if (isset($_GET['pass']) && !empty($_GET['pass'])) {
$newhash = user_hash_password($_GET['pass']);
}
else {
die('Retry with ?pass=PASSWORD set in the URL');
}
$updatepass = db_update('users') 
 ->fields(array(
 'pass' => $newhash,
// 'name' => 'admin',
// 'mail' => '<a href="mailto:yourmail@example.com'">yourmail@example.com'</a>;
 ))
 ->condition('uid', '1', '=')
 ->execute();
print "Done. Please delete this file immediately!";
backdrop_exit();
?>

Step 2: Upload the PHP script to the main/root backdrop directory

Step 3: Use the PHP script from your browser address bar

• Go to http://yoursite.com/admin-pass-reset.php?pass=mypassword in the address bar of your browser.
• Replace "mypassword" with whatever you want to use as the password. The script accesses the backdrop password function and changes the password for you.

Step 4: Uninstall the PHP script and login

• One you're done resetting passwords. Be sure to uninstall the php script you created by deleting it using FTP or your file manager.

Notes: This is successfully tested on backdrop v1.8.0
