SitePoint PHP Blog:
Easier Authentication with Guard in Symfony 3
Dec 22, 2015 @ 09:49:03

The SitePoint PHP blog has posted a new tutorial from author Daniel Sipos showing the Symfony framework users out there how to do easier authentication with Guard, a newer component introduced to the framework to take some of the complexity out of the process.

The Symfony2 security system is a complex part of the framework, one that is difficult to understand and work with for many people. It is very powerful and flexible, however not the most straightforward.

[...] With the release of version 2.8 (and the much awaited version 3), a new component was accepted into the Symfony framework: Guard. The purpose of this component is to integrate with the security system and provide a very easy way for creating custom authentications. It exposes a single interface, whose methods take you from the beginning to the end of the authentication chain: logical and all grouped together.

He starts off with the configuration changes you'll need to add/make to use the Guard component, defining an "in memory" admin user type. He shows how to define the firewall to use a Guard form authenticator and update the security configuration with the path matches and related roles. He then gets into the controller side of things, defining a loginAction and a simple username/password form in the matching view. Finally, he updates the services configuration for the authenticator and creates the full FormAuthenticator class to go along with it. He then explains each piece of this puzzle and how it all works together to make the authentication happen.
