Laravel 5.3 Password Broker Customization

Question

Does anyone know how to override the functions used within laravel's password broker? I know the docs:

https://laravel.com/docs/5.3/passwords#resetting-views

Give information on what to do for things like views and a few surface level things but it's not clear at all really or maybe I'm not reading it enough times.

I already know how to override the ResetsPasswords.php Trait but overriding the functionality of the Password::broker() is for the next layer in.

If there is more information needed I can kindly provide some.

Thank you in advance.

I had to face the same issue, needed to override some of the PasswordBroker functions. After a lot of investigation on the web and many failed attempts to do so, I ended up to the following implementation:

1. Created a CustomPasswordResetServiceProvider inside App\Providers where I registered a CustomPasswordBrokerManager instance.

   namespace App\Providers;
   use Illuminate\Support\ServiceProvider;
   use App\Services\CustomPasswordBrokerManager; 
   class CustomPasswordResetServiceProvider extends ServiceProvider{
       protected $defer = true;
   
       public function register()
       {
           $this->registerPasswordBrokerManager();
       }
   
       protected function registerPasswordBrokerManager()
       {
           $this->app->singleton('auth.password', function ($app) {
               return new CustomPasswordBrokerManager($app);
           });
       }
   
       public function provides()
       {
           return ['auth.password'];
       }
   }
   

2. In config/app.php commented out line:
   //Illuminate\Auth\Passwords\PasswordResetServiceProvider::class,
   and added:
   App\Providers\CustomPasswordResetServiceProvider::class,

3. Inside App\Services folder created a CustomPasswordBrokerManager and copied the context of the default PasswordBrokerManager located at:
   Illuminate\Auth\Passwords\PasswordBrokerManager.php
   Then modified the function resolve to return an instance of my CustomPasswordProvider class.

   protected function resolve($name)
   {
       $config = $this->getConfig($name);
       if (is_null($config)) {
           throw new InvalidArgumentException("Password resetter [{$name}] is not defined.");
       }
   
       return new CustomPasswordBroker(
           $this->createTokenRepository($config),
           $this->app['auth']->createUserProvider($config['provider'])
   );
   }
   

4. Finally inside App\Services folder I created a CustomPasswordBroker class which extends default PasswordBroker located at:
   Illuminate\Auth\Passwords\PasswordBroker and overridden the functions that I needed.

   use Illuminate\Auth\Passwords\PasswordBroker as BasePasswordBroker;    
   
   class CustomPasswordBroker extends BasePasswordBroker    
   {    
   // override the functions that you need here    
   }      
   

Not sure if this is the best implementation but it worked for me.

There are some missing things for step 1 & 3 in the answer https://stackoverflow.com/a/42855948/2311074

Step 1

Probably the safest way is to simply copy the class from Illuminate\Auth\Passwords\PassswordResetServiceProvider.php to App\Provider\CustomPasswordResetServiceProviderand change:

1. Namespace to namespace App\Providers;
2. Class name to CustomPasswordResetServiceProvider
3. Add use App\Services\CustomPasswordBrokerManager; to the top
4. Inside the function registerPasswordBroker rename PasswordBrokerManager to CustomPasswordBrokerManager

Step 2.

Besides changing the resolve method also do the following:

1. Change namespace to namespace App\Services;
2. Add use Illuminate\Auth\Passwords\DatabaseTokenRepository; to the top
3. Change class name to CustomPasswordBrokerManager

This is a very similar implementation that I ended up doing. Very well explained with identification to the directories and all. +1 and marked Correct!

Just had to change the required password length for password resets. The min length of 6 characters is burried quite deep in the laravel code so that I could only change it with your answer here. Thank you so much!

Thank you for this. I was getting stuck on with this Password Broker and Password Broker Manager mess. Seriously, I can't comprehend how they complicated something that used to be simple in such a bad way. Also, for people doing this on Laravel 5.4 there's a slight difference for the register method of the service provider than what's shown here. Essentially, the registerPasswordBroker method should be copied as is on Illuminate\Auth\Passwords\PasswordResetServiceProvider except the part where you use your own custom CustomPasswordBrokerManager instance.
