$hashed_password = hash(config('var.default_hash'), $request['password']);
$request['password'] = $hashed_password;

I think you should create an array like this
if (Auth::attempt(['email' => $email, 'password' => $password, 'active' => 1])) {
// Authentication was successful...
}
you need to change the username to email
then password_hash to password and you need to change your database user table.
