The core library of the Symfony Security component, providing infrastructure for authentication tokens, user providers, role hierarchies, and voter-based authorization decisions in PHP applications. It decouples authorization logic from credential storage and can be used standalone or within the Symfony framework.

Use cases

• implement role-based access control in a php application
• build a custom authorization system with voters
• manage user roles and role hierarchies
• separate authorization logic from user credential providers
• check user permissions programmatically
• add authentication tokens to a non-framework php project

When to choose

• you need fine-grained, testable authorization logic in PHP
• you use Symfony and want the framework's security core
• you want a standalone security library without a full framework

When to avoid

• you need full HTTP firewall, login forms, and session handling (use symfony/security-http or the full framework)
• your project is not PHP-based
• you only need simple hardcoded permission checks
