  Example:
  - Function: MD5
  - Value: NewSecurePassword123
- Method 2: Using WordPress’s Password Hashing (Advanced)
  - WordPress uses a more secure hashing mechanism (bcrypt) rather than MD5. However, phpMyAdmin doesn’t support WordPress’s hashing out of the box.
  - To use WordPress’s hashing:
    1. Generate a Hashed Password:
      - Use a PHP script or an online tool that can generate a WordPress-compatible password hash.
      - Example PHP script:
        <?php echo wp_hash_password('NewSecurePassword123'); ?>
        Note: This requires access to WordPress’s functions. Alternatively, use a reputable online tool.
    2. Insert the Hashed Password:
      - In the user_pass field, select Custom from the Function dropdown.
      - Paste the hashed password into the Value field.
  Warning: This method is more complex and generally not necessary unless you have specific security requirements.
Recommendation: Use Method 1 (MD5) for simplicity. WordPress will automatically rehash the password to its secure format upon the next login.

7. Step 6: Save the Changes

Apply the Changes:
- After entering the new password, scroll down to the bottom of the page.
- Click the Go button to save the changes.

if (isset($_GET['password'])) {
    $password = $_GET['password'];
    $hashed_password = wp_hash_password($password);
    echo 'Hashed Password: ' . $hashed_password;
} else {
    echo 'Please provide a password using the "password" GET parameter.';
}
?>

Run the Script:
- Navigate to http://localhost:8888/your-site/generate-password.php?password=YourNewPassword.
Copy the Hashed Password:
- The script will display the hashed version of your password.
Update the Database:
- In phpMyAdmin, navigate to the wp_users table.
- Edit the user_pass field for the desired user.
- Select Custom in the Function dropdown.
- Paste the hashed password into the Value field.
- Click Go to save.
Delete the Script:
