What is wrong with PDO?

Question

PHP

I can't figure out what I'm doing wrong.
There is in the database, for example, the login admin and the password admin
In the form I enter the login admin and the password admin

include_once 'connectDB.php';
    
if (isset($_POST['entry'])) {
    $login = $_POST['login'];    
    $password = password_hash($_POST['password'], PASSWORD_BCRYPT, ['cost' => 12]);
    $sql = $pdo->prepare("SELECT login, password FROM dataname WHERE login=? AND password=?");
    $sql->execute([$login, $password]);
    $data = $sql->fetch();

    if ($data['login'] == $login and $data['password'] == $password) {        
        echo 'YES';
    }
    else {
        echo 'NO';
    }
}

and he writes to me that there is no such thing, as I understand that something does not match.
and if I remove the password, then the logins are the same

include_once 'connectDB.php';
    
if (isset($_POST['entry'])) {
    $login = $_POST['login'];    
    $password = password_hash($_POST['password'], PASSWORD_BCRYPT, ['cost' => 12]);
    $sql = $pdo->prepare("SELECT login FROM dataname WHERE login=?");
    $sql->execute([$login]);
    $data = $sql->fetch();

    if ($data['login'] == $login) {        
        echo 'YES';
    }
    else {
        echo 'NO';
    }
}

    if(!empty($login)) {
        $sql = $pdo->prepare("INSERT INTO dataname(login, password) VALUES (?, ?)");
        $sql->execute([$login, $password]);           
        echo "YES" ;
    }
    else {
        echo "NO";
    }

password_hash generates different strings every time. use password_verify to verify.

include_once 'connectDB.php';
    
if (isset($_POST['entry'])) {
    $login = $_POST['login'];    
    $sql = $pdo->prepare("SELECT login, password FROM dataname WHERE login=?");
    $sql->execute([$login]);
    $data = $sql->fetch();

    if (password_verify($_POST['password'], $data['password'])) {        
        echo 'YES';
    }
    else {
        echo 'NO';
    }
}
