Hello, what is the set value of public string $hashAlgorithm
in file app/Config/Auth.php?
Please set

public string $hashAlgorithm = PASSWORD_DEFAULT;

If the problem is not solved, please provide more about the PHP version,Sheild version, how to install and etc?

[paul45]

yes $hashAlgorithm is PASSWORD_DEFAULT

PHP: 7.4.0 — CodeIgniter: 4.2.1
shield 1.0 beta

maybe it is a issue with codeigniter4/settings 2.1

Install the latest dev-develop and run php spark shield:setup.
See https://github.com/codeigniter4/shield/blob/develop/docs/install.md#important-composer-error

[paul45]

i have juste install Shield and the error occurred on each page before the Controllers file

[paul45]

before shield i use myth/Auth and i have remove the package

Probably your PHP is too old.

PASSWORD_DEFAULT was int 1; now is string '2y' (in PHP 7.4.0, 7.4.1, and 7.4.2 it was null)
https://www.php.net/manual/en/migration74.incompatible.php#migration74.incompatible.core.password-algorithm-constants

Please try to check the value of PASSWORD_DEFAULT.

i have change
public string $hashAlgorithm = PASSWORD_DEFAULT;
to
public string $hashAlgorithm = PASSWORD_BCRYPT;
in CodeIgniter\Shield\Config\Auth.php

because when i change in App\Config\Auth.php the value of hashAlgorithm don't change

[datamweb]

Is file App/Config/Auth.php as below?
If yes, it shouldn't be a problem, I checked and by changing public string $hashAlgorithm = PASSWORD_DEFAULT; in file App/Config/Auth.php,

these changes are applied to the shield

I will correct it, it does not apply.

<?php

namespace Config;

use CodeIgniter\Shield\Config\Auth as ShieldAuth;
use CodeIgniter\Shield\Authentication\Actions\ActionInterface;
use CodeIgniter\Shield\Authentication\AuthenticatorInterface;
use CodeIgniter\Shield\Authentication\Authenticators\AccessTokens;
use CodeIgniter\Shield\Authentication\Authenticators\Session;
use CodeIgniter\Shield\Authentication\Passwords\ValidatorInterface;
use CodeIgniter\Shield\Models\UserModel;

class Auth extends ShieldAuth
{

[paul45]

yes the file is like this
