Medievalcities were fortified against attack by high walls, and volunteers may fortify a levee against an overflowing river by means of sandbags. Foods can be fortified by adding vitamins, but "fortified wines", such as sherry and port, have brandy (a "stronger" drink) rather than vitamins added to them. By adopting good exercise habits, you can fortify your body against illness. And fortifying needn't always be physical. An author's reputation may be fortified by the success of his new book, or a prosecutor can fortify a case against a suspect by finding more evidence.

Laravel Fortify is a frontend agnostic authentication backend implementation for Laravel. Fortify registers the routes and controllers needed to implement all of Laravel's authentication features, including login, registration, password reset, email verification, and more. After installing Fortify, you may run the route:list Artisan command to see the routes that Fortify has registered.


Since Fortify does not provide its own user interface, it is meant to be paired with your own user interface which makes requests to the routes it registers. We will discuss exactly how to make requests to these routes in the remainder of this documentation.


As mentioned previously, Laravel Fortify is a frontend agnostic authentication backend implementation for Laravel. Fortify registers the routes and controllers needed to implement all of Laravel's authentication features, including login, registration, password reset, email verification, and more.


You are not required to use Fortify in order to use Laravel's authentication features. You are always free to manually interact with Laravel's authentication services by following the documentation available in the authentication, password reset, and email verification documentation.


If you are new to Laravel, you may wish to explore the Laravel Breeze application starter kit before attempting to use Laravel Fortify. Laravel Breeze provides an authentication scaffolding for your application that includes a user interface built with Tailwind CSS. Unlike Fortify, Breeze publishes its routes and controllers directly into your application. This allows you to study and get comfortable with Laravel's authentication features before allowing Laravel Fortify to implement these features for you.


Laravel Fortify essentially takes the routes and controllers of Laravel Breeze and offers them as a package that does not include a user interface. This allows you to still quickly scaffold the backend implementation of your application's authentication layer without being tied to any particular frontend opinions.


You may be wondering when it is appropriate to use Laravel Fortify. First, if you are using one of Laravel's application starter kits, you do not need to install Laravel Fortify since all of Laravel's application starter kits already provide a full authentication implementation.


If you are not using an application starter kit and your application needs authentication features, you have two options: manually implement your application's authentication features or use Laravel Fortify to provide the backend implementation of these features.


If you choose to manually interact with Laravel's authentication services instead of using Fortify, you may do so by following the documentation available in the authentication, password reset, and email verification documentation.


Some developers become confused regarding the difference between Laravel Sanctum and Laravel Fortify. Because the two packages solve two different but related problems, Laravel Fortify and Laravel Sanctum are not mutually exclusive or competing packages.


Laravel Sanctum is only concerned with managing API tokens and authenticating existing users using session cookies or tokens. Sanctum does not provide any routes that handle user registration, password reset, etc.


If you are attempting to manually build the authentication layer for an application that offers an API or serves as the backend for a single-page application, it is entirely possible that you will utilize both Laravel Fortify (for user registration, password reset, etc.) and Laravel Sanctum (API token management, session authentication).


This command will publish Fortify's actions to your app/Actions directory, which will be created if it does not exist. In addition, the FortifyServiceProvider, configuration file, and all necessary database migrations will be published.


The fortify configuration file contains a features configuration array. This array defines which backend routes / features Fortify will expose by default. If you are not using Fortify in combination with Laravel Jetstream, we recommend that you only enable the following features, which are the basic authentication features provided by most Laravel applications:


By default, Fortify defines routes that are intended to return views, such as a login screen or registration screen. However, if you are building a JavaScript driven single-page application, you may not need these routes. For that reason, you may disable these routes entirely by setting the views configuration value within your application's config/fortify.php configuration file to false:


If you choose to disable Fortify's views and you will be implementing password reset features for your application, you should still define a route named password.reset that is responsible for displaying your application's "reset password" view. This is necessary because Laravel's Illuminate\Auth\Notifications\ResetPassword notification will generate the password reset URL via the password.reset named route.


To get started, we need to instruct Fortify how to return our "login" view. Remember, Fortify is a headless authentication library. If you would like a frontend implementation of Laravel's authentication features that are already completed for you, you should use an application starter kit.


All of the authentication view's rendering logic may be customized using the appropriate methods available via the Laravel\Fortify\Fortify class. Typically, you should call this method from the boot method of your application's App\Providers\FortifyServiceProvider class. Fortify will take care of defining the /login route that returns this view:


Your login template should include a form that makes a POST request to /login. The /login endpoint expects a string email / username and a password. The name of the email / username field should match the username value within the config/fortify.php configuration file. In addition, a boolean remember field may be provided to indicate that the user would like to use the "remember me" functionality provided by Laravel.


If the login attempt is successful, Fortify will redirect you to the URI configured via the home configuration option within your application's fortify configuration file. If the login request was an XHR request, a 200 HTTP response will be returned.


If the request was not successful, the user will be redirected back to the login screen and the validation errors will be available to you via the shared $errors Blade template variable. Or, in the case of an XHR request, the validation errors will be returned with the 422 HTTP response.


Fortify will automatically retrieve and authenticate the user based on the provided credentials and the authentication guard that is configured for your application. However, you may sometimes wish to have full customization over how login credentials are authenticated and users are retrieved. Thankfully, Fortify allows you to easily accomplish this using the Fortify::authenticateUsing method.


This method accepts a closure which receives the incoming HTTP request. The closure is responsible for validating the login credentials attached to the request and returning the associated user instance. If the credentials are invalid or no user can be found, null or false should be returned by the closure. Typically, this method should be called from the boot method of your FortifyServiceProvider:


You may customize the authentication guard used by Fortify within your application's fortify configuration file. However, you should ensure that the configured guard is an implementation of Illuminate\Contracts\Auth\StatefulGuard. If you are attempting to use Laravel Fortify to authenticate an SPA, you should use Laravel's default web guard in combination with Laravel Sanctum.


Laravel Fortify authenticates login requests through a pipeline of invokable classes. If you would like, you may define a custom pipeline of classes that login requests should be piped through. Each class should have an __invoke method which receives the incoming Illuminate\Http\Request instance and, like middleware, a $next variable that is invoked in order to pass the request to the next class in the pipeline.


To define your custom pipeline, you may use the Fortify::authenticateThrough method. This method accepts a closure which should return the array of classes to pipe the login request through. Typically, this method should be called from the boot method of your App\Providers\FortifyServiceProvider class.


Some applications may require a different approach to throttling authentication attempts, such as throttling by IP address alone. Therefore, Fortify allows you to specify your own rate limiter via the fortify.limiters.login configuration option. Of course, this configuration option is located in your application's config/fortify.php configuration file.


If the login attempt is successful, Fortify will redirect you to the URI configured via the home configuration option within your application's fortify configuration file. If the login request was an XHR request, a 200 HTTP response will be returned. After a user logs out of the application, the user will be redirected to the / URI.


If you need advanced customization of this behavior, you may bind implementations of the LoginResponse and LogoutResponse contracts into the Laravel service container. Typically, this should be done within the register method of your application's App\Providers\FortifyServiceProvider class:
