## What it is
The Symfony Security Component provides a complete authentication and authorization system for PHP web applications. It supports HTTP basic auth, interactive form login, X.509 certificate login, custom authentication strategies, and role-based authorization.

## Use cases
- add login and authentication to a php web app
- implement role-based access control in symfony
- secure endpoints with http basic auth
- build custom authentication strategies in php
- manage user roles and permissions
- add csrf protection to login forms

## When to choose
- you are building a Symfony application and need authentication/authorization
- you want a mature, well-documented PHP security system with flexible authenticators
- you need role- or voter-based authorization integrated with your framework

## When to avoid
- you use a different framework with its own auth stack (e.g., Laravel's built-in auth)
- you need a standalone identity provider or SSO server rather than an in-app security layer
- you want a zero-config auth solution without framework integration

## Facets
- artifact type: library
- maturity: stable
- function: auth, authorization, security, middleware
- domain: security, web-development, backend, developer-tools
- platform: php, self-hosted
- tags: symfony, authentication, roles, firewalls, voters, csrf, http-basic-auth, form-login, symfony-component, web-server
