Problem authenticating with username and password in Laravel 8

问题

I recently started using Laravel 8 and I am trying to log in using username and email together but I do not know how to do this. In Laravel 7 I could use...

protected function credentials(Request $request)
{
    $field = filter_var($request->get($this->username()), FILTER_VALIDATE_EMAIL)
        ? $this->username()
        : 'username';
    
    return [
        $field => $request->get($this->username()),
        'password' => $request->password,
    ];
}

How can I log in using both username and password in Laravel 8 since there is no LoginController inside the Auth folder anymore?

Solution working for Laravel-Jetstream

You can authenticate using username or email following this steps.

1. Confirm login input field name (Let name is identity)

2. Change config/fortify.php

'username' => 'email' to  'username' => 'identity'

3. Added following authentication code in your app/Providers/FortifyServiceProvider.php file inside boot method

Fortify::authenticateUsing(function (LoginRequest $request) {
            $user = User::where('email', $request->identity)
                ->orWhere('username', $request->identity)->first();

            if (
                $user &&
                \Hash::check($request->password, $user->password)
            ) {
                return $user;
            }
        });

[Note] Please use those classes

use Laravel\Fortify\Http\Requests\LoginRequest;
use App\Models\User;

#For register username

1. Add input in your register.blade.php

<div class="mt-4">
            <x-jet-label for="username" value="{{ __('User Name') }}" />
            <x-jet-input id="username" class="block mt-1 w-full" type="text" name="username" :value="old('username')" required autofocus autocomplete="username" />
</div>

2. Add username in User model $fillable array list.

3. Finally change in app/Actions/Fortify/CreateNewUser.php file

Validator::make($input, [
            ..........
            'username' => ['required', 'string', 'max:255', 'unique:users'],
            .........
        ])->validate();

        return User::create([
           .......
            'username' => $input['username'],
            .....
        ]);
    }

Lets enjoy the authentication.

Laravel Jetstream (available for Laravel 8) replaces Laravel Authentication UI which was available for previous Laravel versions. This means, for the authentication functionality you want, you have to install and use Jetstream. To install Jetstream with composer, run the following command

composer require laravel/jetstream
php artisan jetstream:install

Then, depending on whether you want to use Livewire or Inertia, run one of the following two commands:

php artisan jetstream:install livewire

php artisan jetstream:install inertia

After that, then run

npm install && npm run dev
php artisan migrate

Jetstream is ready for use.

Here is Jetstream documentation and a quick tutorial.
