The Security component provides a complete security system for your web application. It ships with facilities for authenticating using HTTP basic or digest authentication, interactive form login or X.509 certificate login, but also allows you to implement your own authentication strategies. Furthermore, the component provides ways to authorize authenticated users based on their roles, and it contains an advanced ACL system.
You can install the component in 2 different ways:
- Install it via Composer (
- Use the official Git repository (https://github.com/symfony/security).
Then, require the
vendor/autoload.php file to enable the autoloading mechanism
provided by Composer. Otherwise, your application won't be able to find the classes
of this Symfony component.
