- ✅ Invalidated after too many failed attempts
- ✅ Detailed error messages
- ✅ Customizable mail template
- ✅ Auditable logs
Installation
1. Install the package via composer:
composer require benbjurstrom/otpz
2. Publish and run the migrations
php artisan vendor:publish --tag="otpz-migrations"
php artisan migrate
3. Add the package's interface and trait to your Authenticatable model
// app/Models/User.php namespace App\Models; //... use BenBjurstrom\Otpz\Models\Concerns\HasOtps; use BenBjurstrom\Otpz\Models\Concerns\Otpable; class User extends Authenticatable implements Otpable { use HasFactory, Notifiable, HasOtps; // ... }
4. Add the package provided routes
// routes/web.php Route::otpRoutes();
5. (Optional) Publish the views for custom styling
php artisan vendor:publish --tag="otpz-views"
This package publishes the following views:
resources/ └── views/ └── vendor/ └── otpz/ ├── otp.blade.php (for entering the OTP) ├── components/template.blade.php └── mail/ ├── notification.blade.php (standard template) └── otpz.blade.php (custom template)
6. (Optional) Publish the config file
php artisan vendor:publish --tag="otpz-config"
This is the contents of the published config file:
<?php return [ /* |-------------------------------------------------------------------------- | Expiration and Throttling |-------------------------------------------------------------------------- | | These settings control the security aspects of the generated codes, | including their expiration time and the throttling mechanism to prevent | abuse. | */ 'expiration' => 5, // Minutes 'limits' => [ ['limit' => 1, 'minutes' => 1], ['limit' => 3, 'minutes' => 5], ['limit' => 5, 'minutes' => 30], ], /* |-------------------------------------------------------------------------- | Model Configuration |-------------------------------------------------------------------------- | | This setting determines the model used by Otpz to store and retrieve | one-time passwords. By default, it uses the 'App\Models\User' model. | */ 'models' => [ 'authenticatable' => env('AUTH_MODEL', App\Models\User::class), ], /* |-------------------------------------------------------------------------- | Mailable Configuration |-------------------------------------------------------------------------- | | This setting determines the Mailable class used by Otpz to send emails. | Change this to your own Mailable class if you want to customize the email | sending behavior. | */ 'mailable' => BenBjurstrom\Otpz\Mail\OtpzMail::class, /* |-------------------------------------------------------------------------- | Template Configuration |-------------------------------------------------------------------------- | | This setting determines the email template used by Otpz to send emails. | Switch to 'otpz::mail.notification' if you prefer to use the default | Laravel notification template. | */ 'template' => 'otpz::mail.otpz', // 'template' => 'otpz::mail.notification', ];
Usage
Laravel Breeze Livewire Example
- Replace the Breeze provided App\Livewire\Forms\LoginForm::authenticate method with a sendEmail method that runs the SendOtp action. Also be sure to remove password from the LoginForm's properties.
// app/Livewire/Forms/LoginForm.php use BenBjurstrom\Otpz\Actions\SendOtp; use BenBjurstrom\Otpz\Exceptions\OtpThrottleException; use BenBjurstrom\Otpz\Models\Otp; //... #[Validate('required|string|email')] public string $email = ''; #[Validate('boolean')] public bool $remember = false; //... public function sendEmail(): Otp { $this->validate(); $this->ensureIsNotRateLimited(); RateLimiter::hit($this->throttleKey(), 300); try { $otp = (new SendOtp)->handle($this->email, $this->remember); } catch (OtpThrottleException $e) { throw ValidationException::withMessages([ 'form.email' => $e->getMessage(), ]); } RateLimiter::clear($this->throttleKey()); return $otp; }
- Update resources/views/livewire/pages/auth/login.blade.php such that the login function calls our new sendEmail method and redirects to the OTP entry page. You can also remove the password input field in this same file.
public function login(): void { $this->validate(); $otp = $this->form->sendEmail(); $this->redirect($otp->url); }
Laravel Breeze Inertia Example
- Replace the Breeze provided App\Http\Requests\Auth\LoginRequest::authenticate method with a sendEmail method that runs the SendOtp action. Also be sure to remove password from the rules array.
// app/Http/Requests/Auth/LoginRequest.php use BenBjurstrom\Otpz\Actions\SendOtp; use BenBjurstrom\Otpz\Exceptions\OtpThrottleException; use BenBjurstrom\Otpz\Models\Otp; //... public function rules(): array { return [ 'email' => ['required', 'string', 'email'] ]; } //... public function sendEmail(): Otp { $this->ensureIsNotRateLimited(); RateLimiter::hit($this->throttleKey(), 300); try { $otp = (new SendOtp)->handle($this->email, $this->remember); } catch (OtpThrottleException $e) { throw ValidationException::withMessages([ 'email' => $e->getMessage(), ]); } RateLimiter::clear($this->throttleKey()); return $otp; }
- Update the App\Http\Controllers\Auth\AuthenticatedSessionController::store method to call our new sendEmail method and redirect to the OTP entry page.
public function store(LoginRequest $request): \Symfony\Component\HttpFoundation\Response { $otp = $request->sendEmail(); return Inertia::location($otp->url); }
- Remove the password input field from the resources/js/Pages/Auth/Login.vue file.
Everything else is handled by the package components.
