description	Laravel Fortify headless authentication backend development. Activate when implementing authentication features including login, registration, password reset, email verification, two-factor authentication (2FA/TOTP), profile updates, headless auth, authentication scaffolding, or auth guards in Laravel applications.

Laravel Fortify Development

Fortify is a headless authentication backend that provides authentication routes and controllers for Laravel applications.

Documentation

Use search-docs for detailed Laravel Fortify patterns and documentation.

Usage

• Routes: Use list-routes with only_vendor: true and action: "Fortify" to see all registered endpoints
• Actions: Check app/Actions/Fortify/ for customizable business logic (user creation, password validation, etc.)
• Config: See config/fortify.php for all options including features, guards, rate limiters, and username field
• Contracts: Look in Laravel\Fortify\Contracts\ for overridable response classes (LoginResponse, LogoutResponse, etc.)
• Views: All view callbacks are set in FortifyServiceProvider::boot() using Fortify::loginView(), Fortify::registerView(), etc.

Available Features

Enable in config/fortify.php features array:

• Features::registration() - User registration
• Features::resetPasswords() - Password reset via email
• Features::emailVerification() - Requires User to implement MustVerifyEmail
• Features::updateProfileInformation() - Profile updates
• Features::updatePasswords() - Password changes
• Features::twoFactorAuthentication() - 2FA with QR codes and recovery codes

Use search-docs for feature configuration options and customization patterns.

Setup Workflows

Two-Factor Authentication Setup

- [ ] Add TwoFactorAuthenticatable trait to User model
- [ ] Enable feature in config/fortify.php
- [ ] If the `*_add_two_factor_columns_to_users_table.php` migration is missing, publish via `php artisan vendor:publish --tag=fortify-migrations` and migrate
- [ ] Set up view callbacks in FortifyServiceProvider
- [ ] Create 2FA management UI
- [ ] Test QR code and recovery codes

Use search-docs for TOTP implementation and recovery code handling patterns.

Email Verification Setup

- [ ] Enable emailVerification feature in config
- [ ] Implement MustVerifyEmail interface on User model
- [ ] Set up verifyEmailView callback
- [ ] Add verified middleware to protected routes
- [ ] Test verification email flow

Use search-docs for MustVerifyEmail implementation patterns.

Password Reset Setup

- [ ] Enable resetPasswords feature in config
- [ ] Set up requestPasswordResetLinkView callback
- [ ] Set up resetPasswordView callback
- [ ] Define password.reset named route (if views disabled)
- [ ] Test reset email and link flow

Use search-docs for custom password reset flow patterns.

SPA Authentication Setup

- [ ] Set 'views' => false in config/fortify.php
- [ ] Install and configure Laravel Sanctum for session-based SPA authentication
- [ ] Use the 'web' guard in config/fortify.php (required for session-based authentication)
- [ ] Set up CSRF token handling
- [ ] Test XHR authentication flows

Use search-docs for integration and SPA authentication patterns.

Two-Factor Authentication in SPA Mode

When views is set to false, Fortify returns JSON responses instead of redirects.

If a user attempts to log in and two-factor authentication is enabled, the login request will return a JSON response indicating that a two-factor challenge is required:

{
    "two_factor": true
}

Best Practices

Custom Authentication Logic

Override authentication behavior using Fortify::authenticateUsing() for custom user retrieval or Fortify::authenticateThrough() to customize the authentication pipeline. Override response contracts in AppServiceProvider for custom redirects.

Registration Customization

Modify app/Actions/Fortify/CreateNewUser.php to customize user creation logic, validation rules, and additional fields.

Rate Limiting

Configure via fortify.limiters.login in config. Default configuration throttles by username + IP combination.
