Rehash Password If Needed

Deprecated

This action has been deprecated since version v8.x. Automatic password rehashing has become a default part of Laravel. Please see Laravel's documentation for details.

The RehashPasswordIfNeeded action is responsible for rehashing the user's password, when it is required. Internally, the Hasher component is used for determining if the password needs to be rehashed, as well as the actual rehashing.

Caution

While this action will rehash the user's password, it will NOT SAVE the new hashed password! This must be done manually. No assumptions are made regarding how to persist changes on the authenticated user (Authenticatable component).

See password rehashed event, for details.

How to use

The easiest way to enable this action, is by overwriting the default authentication pipelines, in your App\Providers\FortifyServiceProvider.

use Aedart\Auth\Fortify\Actions\RehashPasswordIfNeeded;
use Illuminate\Support\ServiceProvider;
use Laravel\Fortify\Actions\AttemptToAuthenticate;
use Laravel\Fortify\Actions\EnsureLoginIsNotThrottled;
use Laravel\Fortify\Actions\PrepareAuthenticatedSession;
use Laravel\Fortify\Actions\RedirectIfTwoFactorAuthenticatable;
use Laravel\Fortify\Fortify;
use Illuminate\Http\Request;

class FortifyServiceProvider extends ServiceProvider
{
    public function boot(): void
    {
        // ...previous not shown...
        
        // Use custom authentication pipeline...
        Fortify::authenticateThrough(function (Request $request) {
            return array_filter([
                    config('fortify.limiters.login')
                        ? null
                        : EnsureLoginIsNotThrottled::class,

                    Features::enabled(Features::twoFactorAuthentication())
                        ? RedirectIfTwoFactorAuthenticatable::class
                        : null,

                    AttemptToAuthenticate::class,
                    PrepareAuthenticatedSession::class,
                    
                    // Add the rehash password action AFTER user was authenticated!
                    RehashPasswordIfNeeded::class
            ]);
        });
    }
    
    // ...remaining not shown...
}

Password Was Rehashed Event

When the user's password is rehashed, the PasswordWasRehashed event is dispatched. It contains the authenticated user and the rehashed password. You can listen for this event and change your user's current password with a new one, as you see fit.

The following example assumes that an Eloquent Model is used as the application's Authenticatable user.

// ...inside App\Providers\EventServiceProvider...

use Aedart\Auth\Fortify\Events\PasswordWasRehashed;
use Illuminate\Support\Facades\Event;

public function boot(): void
{ 
    Event::listen(function (PasswordWasRehashed $event) {
        $user = $event->user;
 
        $user->forceFill([
            'password' => $event->hashed // the new password hash!
        ])->save();
    });
}
