Warning: mysql_connect(): Access denied for user 'root'@'localhost' (using password: YES)

Warning: mysql_connect(): Access denied for user 'root'@'localhost' (using password: YES) in C:\xampp\htdocs\Login\sessionHandler.php on line 35 So this is what's on the line 35. ``` //to make a connection with database $conn = mysql_connect("localhost", "root", "password") or die(mysql_error()); ``` I don't know whether this is the problem or the code I'm writing. I have searched for every possible answer but it is not what I was looking for. this is my code (if the problem is not really on the line 35) ``` //validation error flag $errflag = false; //Input Validation if($_POST['uname'] == '') { $errmsg_arr[]='Login ID missing'; $errflag = true; } if($_POST['pword'] == '') { $errmsg_arr[] = 'Password missing'; $errflag = true; } //if there are input validations, redirect back to the login form if($errflag) { $_SESSION['ERRMSG_ARR'] = $errmsg_arr; session_write_close(); header("location: login.php"); exit(); } //to make a connection with database $conn = mysql_connect("localhost", "root", "password") or die(mysql_error()); //to select the targeted database mysql_select_db("ngchoonching", $conn) or die(mysql_error()); //to create a query to be executed in sql $username = $_POST['uname']; $password = $_POST['pword']; $query = "SELECT * FROM profile WHERE username = '$username' AND password = '$password'"; //to run sql query in database $result= mysql_query($query, $conn) or die(mysql_error()); //check whether the query was successful or not if(isset($result)) { if(mysql_num_rows($result) == 1) { //Login successful session_regenerate_id(); $member = mysql_fetch_assoc($result); $_SESSION['SESS_MEMBER_ID'] = $member['id']; $_SESSION['SESS_FIRST_NAME'] = $member['firstname']; $_SESSION['SESS_LAST_NAME'] = $member['lastname']; $_SESSION['STATUS'] = true; session_write_close(); header("location: login-successful.php"); exit(); } else { //login failed header("location: login-failed.html"); exit(); } } else { die("Query failed"); } ?> ``` I use localhost,phpmyadmin,xampp and I don't understand why the access is denied.
