Change WP User Password

$user_id = 1; // ID of the user whose password you want to change
$new_password = 'new_secure_password';

// Change the password
wp_set_password($new_password, $user_id);

This will update the password for the user with ID 1 to `'new_secure_password'`.

### Important Notes:
– After changing the password with `wp_set_password`, the user will be logged out, and they'll need to log in with the new password.
– Ensure that the new password meets the WordPress password strength requirements, or use a sufficiently complex password.

If you need to change the password for the current logged-in user, you can use:

$new_password = 'new_secure_password';
wp_set_password($new_password, get_current_user_id());

This will change the password for the currently logged-in user.
