Laravel File system auth

I try build a Laravel authentication application that is based on file system storage and in database based way parallel.

I made a method, like this:

    private function fileAuth(array $credentials): void
    {
        $userFileName = config('backup_values.backup_path') . $credentials['email'] . '.json';
        $user = AuthFileUtils::readFile($userFileName);
        if (Hash::check($credentials['password'], $user->password)) {
            $loggedInUser = new User();
            foreach ($user as $key => $value) {
                $loggedInUser->{$key} = $value;
            };
            Auth::guard('web')->login($loggedInUser);
        } else {
            RateLimiter::hit($this->throttleKey());
            throw ValidationException::withMessages([
                'email' => trans('auth.failed'),
            ]);
        }
    }

I try use Auth::guard(‘web’)->login($loggedInUser) method but it call database query.
Do I need create custom provider? How can I make it in a simply way?
Please help me.

    I made a custom provider and I registered it like this:

    <?php

namespace AppProviders;

use IlluminateSupportFacadesAuth;
use IlluminateSupportFacadesVite;
use IlluminateSupportServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    public function register(): void
    {
        //
    }

    public function boot(): void
    {
        Vite::prefetch(concurrency: 3);

        Auth::provider('custom', function ($app, array $config) {
            return new CustomUserProvider();
        });
    }
}

    The custom provider looks like this:

    <?php

namespace AppProviders;

use AppModelsUser;
use ApputilsAuthFileUtils;
use IlluminateContractsAuthAuthenticatable;
use IlluminateContractsAuthUserProvider;
use IlluminateSupportFacadesHash;

class CustomUserProvider implements UserProvider
{

    public function retrieveById($identifier)
    {

    }

    public function retrieveByToken($identifier, #[SensitiveParameter] $token)
    {

    }

    public function updateRememberToken(Authenticatable $user, #[SensitiveParameter] $token)
    {

    }

    public function retrieveByCredentials(#[SensitiveParameter] array $credentials)
    {
        $fileName = config('backup_values.backup_path') . $credentials['email'] . '.json';
        $userFromFile = AuthFileUtils::readFile($fileName);
        $user = new User();
        foreach ($userFromFile as $key => $value) {
            $user->$key = $value;
        }
        return $user;
    }

    public function validateCredentials(Authenticatable $user, #[SensitiveParameter] array $credentials)
    {
        $result = Hash::check($credentials['password'], $user->getAuthPassword());
        return $result;
    }

    public function rehashPasswordIfRequired(Authenticatable $user, #[SensitiveParameter] array $credentials, bool $force = false)
    {
        $result = $credentials['password'];
        return hash::make($result);
    }
}

    And I set it in auth.php like this:

        'providers' => [
        'users' => [
            'driver' => 'custom',
            'model' => env('AUTH_MODEL', AppModelsUser::class),
        ],
    ],

    But the user not logged in. How can I use it? The methods called in CustomUserProvider and I think result is good, but session not redirected to dashboard.

    I implemented the retrieveById method in my CustomUserProvider:

        public function retrieveById($identifier)
    {
        $dirPath = config('backup_values.backup_path');
        $files = scandir($dirPath);
        foreach ($files as $file) {
            $filePath = $dirPath . '/' . $file;
            if (is_file($filePath)) {
                try {
                    $user = AuthFileUtils::readFile($filePath);
                    if ($user->id == $identifier) {
                        $locatedUser = new User();
                        foreach ($user as $key => $value) {
                            $locatedUser->{$key} = $value;
                        }
                        return $locatedUser;
                    }
                } catch (Exception $e) {

                }
            }
        }
        return null;
    }

    And it looks like work now.
