login with username

[paul45]

I try to use validFields to login with username
the login views only display a email field with email validation

Is this function operational?

Yes, you can.

1. Edit file app/Config/Auth.php

    public array $views = [
        'login'                       => '\App\Views\Shield\login',
    ];

and comment email and uncomment username:

    /**
     * --------------------------------------------------------------------
     * Valid login fields
     * --------------------------------------------------------------------
     * Fields that are available to be used as credentials for login.
     */
    public array $validFields = [
        //'email',
        'username',
    ];

2. copy file vendor\codeigniter4\shield\src\Views\login.php to app\Views\Shield\login.php and edit :

<!-- Email -->
<div class="mb-2">
     <input type="text" class="form-control" name="username" placeholder="<?= lang('Auth.usernam') ?>" value="<?= old('username') ?>" required />
</div>

3. Edit file vendor\codeigniter4\shield\src\Controllers\LoginController.php

    protected function getValidationRules(): array
    {
        return setting('Validation.login') ?? [
            'username' => config('AuthSession')->usernameValidationRules,
           // 'email'    => config('AuthSession')->emailValidationRules,
            'password' => 'required',
        ];
    }

I have not tested but it should work.
In the 3 step, it is better to create a custom login controller (the explanation given is not the right way, it is only for summary)

See https://shield.codeigniter.com/customization/validation_rules/
This is Registration, but you can customize Login validation rules in the same way.

Is it possible to log in with a username or email using the same input box? like GitHub.

Shield ensures you can only use one of those valid fields as a credential during login with the Session controller.
