Reset Joomla Admin Password Using Custom PHP Script

If you’ve lost access to your Joomla admin account and need to reset your password, you can do so using a custom PHP script. Follow the steps below to create and execute the script to reset your Joomla admin password.

Step-by-Step Guide

Step 1: Create the PHP Script

Create a new PHP file (e.g., reset_admin_password.php) and add the following code:

<?php
// Database configuration
$host = 'localhost';
$db = 'your_joomla_database';
$user = 'your_database_username';
$pass = 'your_database_password';
$prefix = 'jos_'; // Change this if your Joomla table prefix is different

// New password
$new_password = 'your_new_password';

// Hash the new password using Joomla's hashing method
$options = [
    'cost' => 10,
];
$hashed_password = password_hash($new_password, PASSWORD_BCRYPT, $options);

// Create a connection to the database
$mysqli = new mysqli($host, $user, $pass, $db);

// Check the connection
if ($mysqli->connect_error) {
    die('Connection failed: ' . $mysqli->connect_error);
}

// Update the admin user password
$sql = "UPDATE " . $prefix . "users SET password = '$hashed_password' WHERE username = 'admin'";

if ($mysqli->query($sql) === TRUE) {
    echo "Password reset successfully!";
} else {
    echo "Error updating password: " . $mysqli->error;
}

// Close the connection
$mysqli->close();
?>

Warning: Replace your_joomla_database, your_database_username, your_database_password, your_new_password, and adjust the table prefix if necessary.

Step 2: Upload the Script

Upload the reset_admin_password.php file to the root directory of your Joomla installation using an FTP client or your hosting control panel’s file manager.

Step 3: Execute the Script

Open your web browser and navigate to the following URL:

http://yourdomain.com/reset_admin_password.php

Make sure to replace yourdomain.com with your actual domain name. You should see a message indicating whether the password reset was successful or if there was an error.

Step 4: Delete the Script

For security reasons, immediately delete the reset_admin_password.php file from your server after resetting your password.

Conclusion

By following these steps, you can reset your Joomla admin password using a custom PHP script. This method is useful if you’ve lost access to your admin account and need to regain control of your Joomla site. Always remember to delete the script after use to maintain the security of your site.
