Error Problem

Hi, I am new anyone knows how to fix this error?

A PHP Error was encountered
Severity: Warning
Message: mysqli::real_connect(): (HY000/1045): Access denied for user 'bi19110176'@localhost (using password: YES)
Filename: mysqli/mysqli_driver.php
Line Number: 201
Backtrace:
File: C:\xampp\xampp\htdocs\webtech2021_BI19110176\application\controllers\Welcome.php
Line: 25
Function: model
File: C:\xampp\xampp\htdocs\webtech2021_BI19110176\index.php
Line: 315
Function: require_once

A Database Error Occurred
Unable to connect to your database server using the provided settings.
Filename: C:/xampp/xampp/htdocs/webtech2021_BI19110176/system/database/DB_driver.php
Line Number: 436

My code:
public function index()
{
//$this->load->database();
//$this->load->view('welcome_message');
$this -> load -> model('Customer','',TRUE);

$this -> Customer -> getCustomers();
}

The reason is in the first line: Access denied for user 'bi19110176'@localhost
Enter the right password for that user and it will connect.

If not running XAMPP then use cmd or terminal.

Code:

// XAMPP - Shell from Control Panel - change root to your user name and password to yours.
cd mysql\bin
mysqladmin --user=root password "password"
