如何仅在 Laravel 中使用 url 和 hash 参数登录？ （没有用户名和密码）

Question

I want to send users link with their own hashes to login without inputing form, I already tried it but it's too slow so I'm not sure if it even works:

web.php

Route::get('link/{hash}', 'Auth\LoginController@loginless')->where('hash', '(.*)');

LoginController.php

public function loginless($hash)
{
    $response           = array();
    $response['status'] = 500;
    $response['url']    = null;
    
    $username = '';
    $password = '';
    $arr_username = User::select('username','password')->get();
    
    foreach ($arr_username as $arr){
        if (Hash::check($arr->username, $hash)){
            $username = $arr->username;
            $password = $arr->password;
            break;
        }
    }

    if (\Auth::attempt(['username' => $username, 'password' => $password])) {
        $response['status'] = 200;
        $response['url']    = route('dashboard');
    }

    return $response;
}

Any way to make it more efficient? (is it possible without foreach?)

In your case, you can use encryption with key, check this
